Meet the New Raspberry Pi 3, Model B+

https://blog.hackster.io/meet-the-new-raspberry-pi-3-model-b-2783103a147
This new version is based around the same 64-bit quad-core Broadcom BCM2837 processor as its predecessor, but now clocked at 1.4GHz rather than 1.2GHz. This means that the new Raspberry Pi board will run only moderately (around 15%) faster. It comes with the same 1GB of LPDDR2 SDRAM as its predecessor.

    How Much Power Does Raspberry Pi 3B+ Use? Power Measurements
    http://raspi.tv/2018/how-much-power-does-raspberry-pi-3b-use-power-measurements

    Since the original Pi came out I’ve been interested in how much power it consumes. It’s become something of a launch week tradition to publish a new chart and some data. So much so that several people ask for it on launch day.

    With just an HDMI screen and a USB keyboard/mouse dongle connected, the Pi is powered using my bench power supply at 5.2V (supply current limit = 3 Amps)

    Raspberry Pi 3B+ uses at least 170 mA more than its older sibling the Pi3B, but can use significantly more when the ARM CPUs are being driven hard.

    Making Custom Silicon For The Latest Raspberry Pi
    https://hackaday.com/2018/04/12/making-custom-silicon-for-the-latest-raspberry-pi/

    The latest Raspberry Pi, the Pi 3 Model B+, is the most recent iteration of hardware from the Raspberry Pi Foundation. No, it doesn’t have eMMC, it doesn’t have support for cellular connectivity, it doesn’t have USB 3.0, it doesn’t have SATA, it doesn’t have PCIe, and it doesn’t have any of the other unrealistic expectations for a thirty-five dollar computer. That doesn’t mean there wasn’t a lot of engineering that went into this new version of the Pi; on the contrary — the latest Pi is filled with custom silicon, new technologies, and it even has a neat embossed RF shield.

    On the Raspberry Pi blog, [James Adams] went over the work that went into what is probably the most significant part of the new Raspberry Pi. It has new, custom silicon in the power supply. This is a chip that was designed for the Raspberry Pi, and it’s a great lesson on what you can do when you know you’ll be making millions of a thing.

    More power to your Pi
    https://www.raspberrypi.org/blog/pi-power-supply-chip/

    It’s been just over three weeks since we launched the new Raspberry Pi 3 Model B+. Although the product is branded Raspberry Pi 3B+ and not Raspberry Pi 4, a serious amount of engineering was involved in creating it. The wireless networking, USB/Ethernet hub, on-board power supplies, and BCM2837 chip were all upgraded: together these represent almost all the circuitry on the board!

    Powering your Pi

    One of the most critical but often under-appreciated elements of any electronic product, particularly one such as Raspberry Pi with lots of complex on-board silicon (processor, networking, high-speed memory), is the power supply. In fact, the Raspberry Pi 3B+ has no fewer than six different voltage rails: two at 3.3V — one special ‘quiet’ one for audio, and one for everything else; 1.8V; 1.2V for the LPDDR2 memory; and 1.2V nominal for the CPU core. Note that the CPU voltage is actually raised and lowered on the fly as the speed of the CPU is increased and decreased depending on how hard the it is working. The sixth rail is 5V, which is the master supply that all the others are created from, and the output voltage for the four downstream USB ports; this is what the mains power adaptor is supplying through the micro USB power connector.

    A history lesson

    The BCM2835 processor chip (found on the original Raspberry Pi Model B and B+, as well as on the Zero products) has on-chip power supplies: one switch-mode regulator for the core voltage, as well as a linear one for the LPDDR2 memory supply. This meant that in addition to 5V, we only had to provide 3.3V and 1.8V on the board, which was relatively simple to do using cheap, off-the-shelf parts.

    When we moved to the BCM2836 for Raspberry Pi Model 2 (and subsequently to the BCM2837A1 and B0 for Raspberry Pi 3B and 3B+), the core supply and the on-chip LPDDR2 memory supply were not up to the job of supplying the extra processor cores and larger memory, so we removed them. (We also used the recovered chip area to help fit in the new quad-core ARM processors.) The upshot of this was that we had to supply these power rails externally for the Raspberry Pi 2 and models thereafter. Moreover, we also had to provide circuitry to sequence them correctly in order to control exactly when they power up compared to the other supplies on the board.

    Power supply design is tricky (but critical)

    In designing the power chain for the Pi 2 and 3, the sequencing was fairly straightforward: power rails power up in order of voltage (5V, 3.3V, 1.8V, 1.2V). However, the supplies were all generated with individual, discrete devices. Therefore, I spent quite a lot of time designing circuitry to control the sequencing

    More complex systems generally use a Power Management Integrated Circuit (PMIC) with multiple supplies on a single chip, and many different PMIC variants are made by various manufacturers. Since Raspberry Pi 2 days, I was looking for a suitable PMIC to simplify the Pi design, but invariably (and somewhat counter-intuitively) these were always too expensive compared to my discrete solution, usually because they came with more features than needed.

    in June 2016 Peter, along with Tuomas Hollman and Trevor Latham, visited to pitch the possibility of building a custom power management solution for us.

    I was initially sceptical that it could be made cheap enough. However, our discussion indicated that if we could tailor the solution to just what we needed, it could be cost-effective. Over the coming weeks and months, we honed a specification we agreed on from the initial sketches we’d made, and Exar thought they could build it for us at the target price.

    The chip we designed would contain all the key supplies required for the Pi on one small device in a cheap QFN package, and it would also perform the required sequencing and voltage monitoring. Moreover, the chip would be flexible to allow adjustment of supply voltages from their default values via I2C

    Raspberry Pi Keeps Cool
    https://hackaday.com/2018/05/22/raspberry-pi-keeps-cool/

    In general, heat is the enemy of electronics. [Christopher Barnatt] is serious about defeating that enemy and did some experiments with different cooling solutions for the Raspberry Pi 3.

    A simple test script generated seven temperature readings for each configuration. [Barnatt] used a bare Pi, a cheap stick-on heatsink, and then two different fans over the heatsink. He also rigged up a large heatsink using a copper spacer and combined it with the larger of the two fans.

    The Raspberry Pi 3B+ As An SDR – Without The SDR!
    https://hackaday.com/2018/04/14/the-raspberry-pi-3b-as-an-sdr-without-the-sdr/

    What about the idea of an SDR without any external hardware? Instead of plugging something into your Raspberry Pi, how about using the Pi itself, unmodified? That’s just what the Nexmon SDR project has achieved, and this has been made possible through clever use of the on-board Broadcom 802.11ac WiFi chip. The result is a TX-capable SDR, albeit one only capable of operating within the 2.4 GHz and 5 GHz spectrum used by WiFi.

    5 Things You Didn’t Know About the Raspberry Pi 3 B+
    https://www.designnews.com/electronics-test/5-things-you-didnt-know-about-raspberry-pi-3-b/172570905259552?ADTRK=UBM&elq_mid=5895&elq_cid=876648

    The Raspberry Pi 3 B+ is a great hobbyist board, but it also has features that allow for developers to build sophisticated automation and IoT devices.

    Since its 2011 inception, the Raspberry Pi Foundation has sold 19 million Raspberry Pis. The first Raspberry Pi was sold on February 29, 2012. With the Raspberry Pi, a variety of projects ranging from internet radios to mobile robots have been built with the $35 credit card size Linux computer. The latest of the Raspberry Pi family of single board computers (SBCs) is the Pi 3 B+. The form factor hasn’t changed, but the Pi 3 B+ system on a chip (SoC) has more computing capabilities than the previous single board computers (SBCs).

    1.) The CPU Is High Power.

    The Raspberry Pi 3 B+ SBC uses a Broadcom BCM2837 SoC. The BCM2837 is like the BCM2836 SoC used in the Pi 2 unit with the exception of the processor. A quad core Cortex A53 (ARMv8) processor is used with the Pi 3 B+ instead of the Pi 2 900 MHz, quad-core ARM Cortex A7 (ARMv7)

    2.) It’s Low Power.

    The traditional method of powering a Raspberry Pi 3 B+ is to use a 5.1V micro USB (type B) connector supply. The current requirement to power the SBC is 2.5A. Most cellphone chargers can provide both the voltage and current to operate the Pi 3 B+.

    3.) GPIO Makes It Ideal for IoT Applications.

    Aside from being a small, powerful computer, the Raspberry Pi 3 B+ can connect and control physical devices—making it an ideal option for DIY Internet of Things (IoT) projects and applications. The general-purpose input output (GPIO) pins allow the SBC to be used in a variety of control applications ranging from home automation to mobile robotics. There is a dual 40 pin male header connector soldered to the Pi 3 B+ printed circuit board (PCB).

    4. It Gives You More USB Options than Ever Before.

    The Raspberry Pi 3 B+ provides four USB 2.0 ports. Those four ports are supported by a LAN9514 combination hub and Ethernet controller integrated circuit (IC).

    5. It Can Be Used in Physical Computing Applications.

    An approach to designing human-computer interface applications consists of understanding human physical characteristics or environmental conditions. Examples of human physical characteristics are hand gestures, breathing, and eye motion. Temperature, pressure, motion, and vibration represent environmental conditions. Physical computing deals with building devices that can sense and respond to human physical characteristics or surrounding environments. Software and hardware circuits allow the sensing and response to human physical characteristics or environmental conditions.

    New Out Of Box Software (NOOBS) is an easy operating system installation manager for the Raspberry Pi.
    https://www.raspberrypi.org/documentation/installation/noobs.md

    SD cards with NOOBS preinstalled are available from many of our distributors and independent retailers, including Pimoroni, Adafruit, and Pi Hut.

    Alternatively, NOOBS is available for download on the Raspberry Pi website: raspberrypi.org/downloads

    Once you’ve downloaded the NOOBS zip file, you’ll need to copy the contents to a formatted SD card on your computer.

    To set up a blank SD card with NOOBS:

    Format an SD card which is 8GB or larger as FAT. See the instructions given below.
    Download and extract the files from the NOOBS zip file.
    Copy the extracted files onto the SD card that you just formatted, so that this file is at the root directory of the SD card. Please note that in some cases it may extract the files into a folder; if this is the case, then please copy across the files from inside the folder rather than the folder itself.
    On first boot, the “RECOVERY” FAT partition will be automatically resized to a minimum, and a list of OSes that are available to install will be displayed.

    If you are a Windows user, we recommend formatting your SD card using the SD Association’s Formatting Tool, which can be downloaded from sdcard.org.
