BeagleBone Black

Beagle Board has a long history of making reasonably ARM development boards. Recently they come up with interesting BeagleBone series of boards.

BeagleBone is an $89 MSRP, credit-card-sized Linux computer that connects to the Internet and runs software such as Android 4.0 and Ubuntu. The board is based on AM335x 720MHz ARM® processor.

BeagleBone Black is a $45 MSRP community-supported development platform for developers and hobbyists. Boot Linux in under 10 seconds and get started on development in less than 5 minutes with just a single USB cable. BeagleBone Black Development Board is based on ARM® Cortex™-A8 processor (1GHz Sitara™ AM335x ARM Cortex-A8). BeagleBone Black ships with the Ångström Linux distribution in onboard FLASH. The board support also for example Ubuntu, Android and Fedora. BeagleBone Black’s capabilities can be extended using plug-in boards called “capes” that can be plugged into BeagleBone Black’s two 46-pin dual-row expansion headers.

From those board BeagleBone Black looks to be more interesting because the Black is more powerful and more capable than its predecessor and it’s cheaper. The other interesting feature is Cloud9 IDE on Node.JS with Bonescript library that allows you to provides several functions useful for interacting with your hardware with web browser and JavaScript code. BoneScript is a node.js-based language specifically optimized for the Beagle family and featuring familiar Arduino function calls, exported to the browser. Performing physical computing tasks in JavaScript looks rather different than C on microcontrollers. JavaScript and the Node.JS interpreter like to do everything asynchronously using callbacks.

The Register has an interesting article Review: Beagleboard Beaglebone Black that compares BeagleBone Black to Raspberry Pi. It says that Comparing the two isn’t entirely invidious: many folk who might have been considering the Pi for use as a very tiny desktop computer or media server, may now be thinking the Black, with its more powerful processor, might not be a better bet. The AM335x is set to clock higher than the Pi’s chip can go – 1GHz compared to 700MHz – but it’s possible to manually clock the Pi up. As two variations on the same theme, the differences between Pi and Black are subtle. The Black is clearly the more suitable device for hardware projects (92 expansion pins on two banks 46-pin female connectors, six serial pins for debugging). The Pi the choice for low-cost educational computing.

The article says that you’ll probably want to try the Black if Android is your thing. There’s a working version of Jelly Bean available for the Black, provided by Texas Instruments in support of its Sitara SoCs.

BeagleBone Black looks like a very interesting product to check out some day.

    Aquire Awesome Audio for BeagleBone

    [Henrik Langer] put his powerful audio acquisition and output board up on, and we thought we’d point it out to you. It’s one of those projects that used to be pro audio just a few years back, but is doable (and affordable) DIY today: dual stereo inputs and four(!) stereo outputs, all sampled at 24 bits and up to 192 kHz. It’s configured as a BeagleBone cape, and comes with a customized Linux distribution for the ‘Bone.

    Spark Gap and Coherer Meet Beagle Bone

    Getting back to basics is a great way to teach yourself about a technology. We see it all the time with computers built from NAND gates or even discrete transistors. It’s the same for radio – stripping it back to the 19th century can really let you own the technology. But if an old-school wireless setup still needs a 21st-century twist to light your fire, try this spark gap transmitter and coherer receiver with a Beagle Bone Morse decoder.

    At its heart, a spark gap transmitter is just a broadband RF noise generator, and as such is pretty illegal to operate these days.

    100% electromechanical transmitter is good for a couple of feet

    The receiver is based on a coherer, a device that conducts electricity only when a passing radio wave disturbs it. [Ashish]’s coherer is a slug of iron filings between two bolts in a plastic tube.

    He also added an optoisolator to condition the receiver’s output for an IO pin on the Beagle, and a Python script to decode the incoming Morse.

    Bela: Real-Time BeagleBone Audio/Analog Cape

    Bela is a cape for the BeagleBone Black that’s aimed at artists and musicians. Actually, the cape is much less than half of the story — the rest is in some clever software and a real-time Linux distribution. But we’re getting ahead of ourselves. Let’s talk hardware first.

    First off, the cape has stereo input and output as well as two amplified speaker outs. It can do all of your audio stuff. It also has two banks of analogue inputs and outputs, each capable of handling eight signals.

    All of these input and output peripherals are hooked up to the BeagleBone’s Programmable Realtime Units (PRUs) — a hardware subsystem that’s independent of the CPU but can work along with it. The PRU is interfaced with the real-time Linux core to give you sub-microsecond response in your application. This is a big deal because a lot of other audio-processing systems have latencies that get into the tens of milliseconds or worse, where it starts to be perceptible as a slight lag by humans.

    Bela Platform for audio

    Bela is an embedded system for real-time audio processing with ultra-low latency. Based on the BeagleBone Black single-board computer and featuring a custom hardware and software environment, Bela integrates audio processing and sensor connectivity in a single high-performance package.

    Bela is an ideal platform for musicians, instrument designers, audio enthusiasts and interactive artists.

    BeagleBone Pin-Toggling Torture Test

    Benchmarks often get criticized for their inability to perfectly model the real-world situations that we’d like them to. So take what follows in the limited scope that it’s intended, and don’t read too much into it. [Joonas Pihlajamaa]’s experiments with toggling a hardware pin as fast as possible on different single-board computers can still show us something.

    The take-home result won’t surprise anyone who’s worked with a single-board computer: the higher-level interfaces are simply slow compared to direct memory-mapped GPIO access. But really slow. We’re talking around 5 kHz from Python or any of the file-based interfaces to the pins versus 3 MHz for direct access. Worse, as you’d expect when a non-realtime operating system is in the middle, there are glitches on the order of ten milliseconds with all the file-based methods.

    This test only tells us so much, though, and it’s not really taking advantage of the BeagleBone Black’s ace in the hole, the PRUs — onboard hardware processors that bring real-time IO capabilities to the system. We’d like to see a re-write of the code to take advantage of libpruio, for instance. A 20 MHz square wave is a piece of cake with the PRUs.

    New Part Day: A BeagleBone On A Chip

    The current crop of ARM single board computers have a lot in common. Everything from the Odroid to the Raspberry Pi are built around Systems on a Chip, a piece of silicon that has just about everything you need to build a bare minimum board. You won’t find many hardware hackers playing around with these chips, though. That would require putting some RAM on the board, and some other high-speed connectors. Until now, the only people building these ARM boards were Real Engineers™, with a salary commensurate of their skills.

    This is now about to change. Octavo Systems has launched a new product that’s more or less a BeagleBone on a chip. If you can handle putting a PCB with a BGA package in a toaster oven, you too can build your own ARM single board computer running Linux.

    Octavo’s new System in Package is the OSD335x family, featuring a Texas Instruments AM335x ARM Cortex A8 CPU, up to 1GB of DDR3, and peripherals that include 114 GPIOs, 6 UARTs, 2 SPIs, 2 I2Cs, 2x Gigabit Ethernet, and USB.

    The chips used in commercially available single board computers like the Pi and BeagleBone have hundreds of passive components sprinkled around the board. This makes designing one of these single board computers challenging,

    Octavo is baking a bunch of these resistors, capacitors, and inductors right into this chip, allowing for extremely minimal boards running Linux.

    A New Era of Integration and Flexibility

    Each OSD335x device incorporates a Texas Instruments AM335x Sitara™ Processor, TPS65217C Power Management IC, TL5209 LDO Voltage Regulator, a DDR3 SDRAM, and over 140 passive components. Since the OSD335x encapsulates the complicated high-speed design of the processor/DDR3 interface, the power management IC, and the complete complement of related capacitors, resistors, and inductors, the final system design is vastly simplified.

    Toy Piano Gets Synth Overhaul

    [Liam] built a polyphonic synth into a toy piano. It’s an impressive build that retains the look and feel of the piano, right down to a laser-etched top panel with knobs that match the glossy black styling.

    The brains of the synthesizer is a Beaglebone Black using the Maximillian synthesis library. To capture the key presses, he used Velostat, a pressure-sensitive material that changes resistance under pressure. This is probably the only toy piano in the world with fully polyphonic velocity and aftertouch

    BeagleBone Green, Now Wireless

    Over the past few years, the BeagleBone ecosystem has grown from the original BeagleBone White, followed two years later by the BeagleBone Black. The Black was the killer board of the BeagleBone family, and for a time wasn’t available anywhere at any price. TI has been kind to the SoC used in the BeagleBone, leading to last year’s release of the BeagleBone Green, The robotics-focused BeagleBone Blue, and the very recent announcement of a BeagleBone on a chip. All these boards have about the same capabilities, targeted towards different use cases


    WirelessAs with any single board computer with a fast ARM chip running Linux, comparisons must be made to the Raspberry Pi. Since this is the first BeagleBone released with wireless connectivity baked into the board, the most logical comparison would be against the recently released Raspberry Pi 3.

    The Pi 3 includes an integrated wireless chipset for 802.11n and Bluetooth 4.1 connectivity. The BeagleBone Green Wireless has this, but also adds 802.11 b and g networks. This gives the BBGW the ability to sense when anyone is using a microwave in the vicinity – a boon for that Internet of Things thing we’ve been hearing so much about.

    Unlike the Pi 3, the BBGW has connections for additional antennas in the form of two u.FL connectors.

    Grove Connectors

    The BeagleBone Green Wireless is a Seeed joint, and as with the original BeagleBone Green, there are Grove connectors right on the edge of the board. These connectors provide one I2C bus and one serial connection each for Seeed Studio’s custom modules.

    We don’t have DE-9 connectors anymore, and a smaller, easier to use connector is appreciated, especially when the connectors are a mere $0.15/piece.

    Then again, the intelligence of a Grove module is purely dependant on the operator. On the BeagleBone Green, there are two Grove connectors, one for I2C, and another for serial.

    The BeagleBone Green Wireless doesn’t really do anything new. The SoC is the same, and of course the PRUs in every BeagleBone are the killer feature for really, really fast digital I/O. The addition of WiFi is nice, and the inclusion of extra antenna connectors phenomenal, but it’s nothing a USB WiFi dongle couldn’t handle.

    Blindingly Fast ADC for Your BeagleBone

    Jason Holt] wrote in to tell about of the release of his PRUDAQ project. It’s a dual-channel 10-bit ADC cape that ties into the BeagleBone’s Programmable Realtime Units (PRUs) to shuttle through up to as much as 20 megasamples per second for each channel. That’s a lot of bandwidth!

    With a bit of PRU code, the data can be shuttled out of the ADC and into the BeagleBone’s memory about as fast as you could wish.


    PRUDAQ is a fast, Free, low-cost ADC board for BeagleBone Black and BeagleBone Green. You can build the board yourself using the Eagle files in the repo, or buy one pre-built from GroupGets.


    Dual-channel simultaneously-sampled 10-bit ADC
    Up to 20MSPS per channel (40MSPS total) (but see below)
    0-2V input voltage range (DC coupled)
    4:1 analog switches in front of each channel provide a total of 8 single-ended analog inputs. (See here for differential input)
    SMA jacks for direct access to the 2 ADC channels
    Flexible clock options:
    External input via SMA jack
    Internal onboard 10MHz oscillator
    Programmable clock from BeagleBone GPIO pins

    The BeagleBone’s programmable real-time units (PRUs) make it possible to capture the 400Mbit/s sample stream into the BeagleBone’s 512MB of main memory.

    BeagleLogic’s PRUDAQ driver provides a /dev/beaglelogic device you can pipe into a file or a python program, and their pre-built system image makes it easy to get the software working.

    PRUDAQ is not an oscilloscope

    If you’re looking for an oscilloscope or a hardened data acquisiton system, this board is probably not what you want:

    We haven’t spent much time interfacing our board with high level tools like GNU Radio
    Input signals outside the 0-2V range may damage the ADC
    Inputs are DC-coupled
    We provide a 1V reference for mid-scale, but it’s unbuffered
    At 40MSPS the 1GHz ARMv7 only has 25 cycles per sample (and at least 25% of that is eaten by DMA overhead)
    Round-robin sampling across the 8 analog inputs is tricky:
    Switching latency makes it hard to sample at high rates
    High sample rates also require a low source impedance (strong input signal) to overcome ~300pF switch and filter capacitance
    As the previous section points out, you can buffer samples into the 512MB of main memory, but there’s no way to get the samples into storage or off the board at the full 40MSPS data rate

    [Ken Shirriff] Demystifies BeagleBone I/O

    If you have ever spent a while delving into the bare metal of talking to the I/O pins on a contemporary microprocessor or microcontroller you will know that it is not always an exercise for the faint-hearted. A host of different functions can be multiplexed behind a physical pin, and once you are looking at the hardware through the cloak of an operating system your careful timing can be derailed in an instant. For these reasons most of us will take advantage of other people’s work and use the abstraction provided by a library or a virtual filesystem path.

    If you have ever been curious enough to peer under the hood of your board’s I/O then you may find [Ken Shirriff]’s latest blog post in which he explores the software stack behind the pins on a BeagleBone Black to be of interest.

    New Part Day: Wireless BeagleBones On A Chip

    The BeagleBone is a very popular single board computer, best applied to real-time applications where you need to blink LEDs really, really fast. Over the years, the BeagleBone has been used for stand-alone CNC controllers, the brains behind very large LED installations, and on rare occasions has been used to drive CRTs. If you just want a small Linux board, get a Pi. If you want to do something interesting with hardware, get a BeagleBone.

    The BeagleBone ecosystem has grown a lot in the last year, from the wireless and Grove connector equipped BeagleBone Green, the robotics-focused BeagleBone Blue, the Zoolander-inspired Blue Steel. Now there’s a new BeagleBone, built around a very interesting System on Module introduced earlier this year.

    The new board is called the BeagleBone Black Wireless, and it brings to the table all you know and love about the BeagleBone. There’s a 1GHz ARM355x with two 32-bit 200MHz PRUs for the real-time pin toggling. RAM is set at 512MB, with 4GB of eMMC Flash and Debian pre-installed, and a microSD card for larger storage options. The new feature is wireless connectivity: a TI WiFi and Bluetooth module with provisions for 802.11s replaces the old Ethernet connector.

    An Even Smaller BeagleBone

    The BeagleBone famously fits in an Altoids tin. Even though we now have BeagleBone Blacks, Blues, and Greens, the form factor for this curiously strong Linux board has remained unchanged, and able to fit inside a project box available at every cash register on the planet. There is another Altoids tin, though. The Altoid mini tin is just over 60×40 mm, and much too small to fit a normal size BeagleBone. [Michael Welling] has designed a new BeagleBone to fit this miniature project box. He’s calling it the Pocketbone, and it’s as small as the mints are strong.

    The Pocketbone is based on the Octavo Systems OSD355x family, better known as the ‘BeagleBone on a chip’. This chip features a TI AM355x ARM Cortex A8, up to 1GB of DDR3 RAM, 114 GPIOs, 6 UARTs, 2 SPIs, 2x Gigabit Ethernet, and USB. It’s housed in a relatively large BGA package that makes routing easy,

    TI Brings DLP Pico Projectors to the Masses
    DMD chip priced under $20

    Texas Instruments’ micro-opto-electromechanical-system-based Digital Light Processor (DLP), with millions of micromirrors per digital micromirror device (DMD) MOEMS chip, revolutionized digital cinema, earning the technology’s inventor an Oscar in 2015. After the 87th Academy Awards ceremony, TI began downsizing its technology for consumers. Today, TI is releasing the 0.2-inch, quarter-million-mirror DLP2000 at a price of less than $20, with an evaluation module (EVM) priced at less than $100, making it the most cost-effective pico-projector enabler to date, according to analysts. Competing units for the consumer market use as few as two raster-scanning mirrors.

    “The new TI DLP LightCrafter Display 2000 is a breakthrough, since it brings the price down to a point that any developer can consider it for their applications,”

    TI is the leading supplier of pico-projector chips, having shipped more than 1 million units in the first half of this year, Abowd said. Most of those units shipped to China, but the devices “are also increasingly popular in the U.S., such as in the ultra-thin pico projector Moto Mod, which snaps on to the Moto Z2 Force Edition smartphone,” she said.

    The DLP solution released today offers “a $19.99 DMD chip plus matching controller, power management, and driver chips,”

    The chip undercuts the price of the previous TI generation’s least expensive model by three times and should enable consumer applications to break the $100 price barrier by Christmas 2017.

    Electronics FUN’s BeagleBone Black-Based Oscilloscope Puts Diagnostics in Your Browser

    Open design requires no software to operate and boasts two channels, 100MHz of bandwidth, and full cross-platform compatibility.

    Belgium-based Electronics FUN is looking to make oscilloscopes more accessible with an Ethernet- or Wi-Fi-connected, smartphone-friendly design built around the open-hardware BeagleBone Black single-board computer (SBC).

    “The core of the scope is a real-time Ethernet-based digital storage oscilloscope (DSO),” the company explains of the project. “It can have an extended function of equivalent-time sampling by hooking up an additional up to 1 GHz sampling head. This perfect collaboration not only allows the scope to trace an input signal in real-time but also offers users an opportunity to catch repetitive high frequency signals.”

    “The DSO part features 8 bits, 250 MS/s, 100 MHz bandwidth, dual channels, external trigger, no troublesome software installation (only web browser needed), software control panel and Wi-Fi-range connectivity. Design files and software code of the DSO part can be shared together with the product. You can easily learn how to DIY your own oscilloscope and upgrade it for the final product.”

    Full documentation for the project, including schematics and the source code which runs on the BeagleBone Black’s PRUs, can be found on the project’s page; assembled boards are available for $130, excluding the BeagleBone Black, from the Electronics FUN Tindie store.

    “This PocketGlitcher is a glitching mod-device. It uses the Texas Instruments PRU [Programmable Real-time Unit] to create deterministic signals (5ns precision, not so bad), associated with determined configs. An analog PCB Cape is then plugged to the PocketBeagle to provide a sufficient glitching effect, once connected to the VDD target. As a result, it is now possible to reactivate the nRF52 debug with a low-cost plug-and-play solution. And the most important, the system fits in a pocket.”
