    Raspberry Pi GPIO Configuration

    GPIO – General Purpose Input/Output, aka “BCM” or “Broadcom”.

    These are the big numbers, e.g. “GPIO 22″. You’ll use these with RPi.GPIO and GPIO Zero.

    Physical – or “Board” correspond to the pin’s physical location on the header. These are the small numbers next to the header, e.g. “Physical Pin 15″.

    Piunora Packs a Raspberry Pi CM4 Into a More Maker-Friendly Format You Might Be Familiar With!

    Piunora puts a Pi CM4 into the Adafruit Metro / Arduino R3 form factor — opening up a whole new world of hardware hackability!

    We knew that back in October of this year — less than a mere three months ago — that the release of the new Raspberry Pi CM4 module was going to make waves in the maker world.

    This tiny little SoM — while really, not much more than a Broadcom breakout board — has given makers the ability to pack a 64-bit, quad-core Arm Cortex-A72 along with a few Gb of RAM, globules eMMC — if you want it — and about a gazillion I/O interfaces (give or take) into almost anywhere that you could fit a half-folded playing card.

    Being an SoM, this product is targeted at being integrated into a base board or some sorts

    Seeed Studio’s Dual Gigabit Ethernet Carrier Board Aims at Raspberry Pi Compute Module 4 Routers

    “The Dual Gigabit Ethernet Carrier Board for the Raspberry Pi Compute Module 4 was designed with soft router applications in mind,” the company explains of its latest product, “featuring dual Gigabit Ethernet ports and dual USB 3.0 ports.”

    “In addition, it also features a rich set of I/O peripherals such as MIPI CSI, MIPI DSI and micro-HDMI for display and camera connectivity, a standard 9-pin USB 3.0 for further USB expansion, microSD card slot and FPC connector. Despite this, the Dual Gigabit Ethernet Carrier Board maintains a small form factor of 75 by 64 by 21mm [around 2.95 x 2.52 x 0.82in] – that’s one third the size of the official I/O Board!”

    The Raspberry Pi can boot off NVMe SSDs now
    March 23, 2021

    When the Compute Module 4 was released (see my CM4 review here), I asked the Pi Foundation engineers when we might be able to boot off NVMe storage, since it was trivially easy to use with the exposed PCIe x1 lane on the CM4 IO Board.

    The initial response in October 2020 was “we’ll see”. Luckily, after more people started asking about it, beta support was added for direct NVMe boot just a couple weeks ago.

  19. Tomi Engdahl says:

    NVMe Boot Finally Comes To The Pi Compute Module 4

    Since the introduction of the Raspberry Pi Compute Module 4, power users have wanted to use NVMe drives with the diminutive ARM board. While it was always possible to get one plugged in through an adapter on the IO Board, it was a bit too awkward for serious use. But as [Jeff Geerling] recently discussed on his blog, we’re not only starting to see CM4 carrier boards with full-size M.2 slots onboard, but the Raspberry Pi Foundation has unveiled beta support for booting from these speedy storage devices.

    UCTRONICS 1U Rackmount kit for Raspberry Pi 3 and 4 that fits a 19 Rack mountable and pretty cool…

    The UCTRONICS 1U Rackmount kit for Raspberry Pi 3 and 4 that fits a 19 Rack mountable and pretty cool. So I needed to move from the stackable Raspberry Pie cluster stand to a rack mount version so I can clear my work bench off some.
    So what I did is go thru some offers and found the UCTRONICS 1U Rack kit for Raspberry Pi 3 and 4 boards. It had to have the key feature I need and also gave me the salability to manage my cabling some. I so bought this kit and here are my results. (Enjoy the video…) So overall it met my needs and also worked ok, it need some minor adjustments but it did job well for my needs. (the free shipping is pretty good too…) I give it a 4 out of five star rating

    Embedded machine learning on Raspberry Pi just became even more accessible thanks to Edge Impulse.

    Behold! Edge Impulse and TinyML on Raspberry Pi

    Embedded machine learning on Raspberry Pi just became even more accessible thanks to Edge Impulse.

    Today we are excited to announce our foray into embedded Linux with official support for the Raspberry Pi 4!

    Now, users of Edge Impulse can select the right processor class for their embedded machine learning applications. Leverage our existing best-in-class support for low-power MCUs or venture into processor classes that run embedded Linux if highest performance is the objective.

    For audio applications, plug a standard USB microphone into one of the available USB slots on the Pi. For sensor fusion, the 40-pin GPIO header on the Pi can be employed to connect to your favorite sensors as well.

    SDKs for Python, Node.js, Go, and C++ are provided so you can easily build your own custom apps for inferencing.

  25. Tomi Engdahl says:

    Today we’re launching Edge Impulse for Linux! A complete set of tools that lets developers build custom ML models that help their devices feel, hear, and see the real world.

    And… we’ve added object detection!

    Compact ClusBerry-2M Packs Two Raspberry Pi Compute Modules 4s for Industrial Clustering Work

    Following the company’s earlier eight-module ClusBerry launch, the ClusBerry-2M scales down to two for a lower-cost cluster.

    Industrial computing specialist TECHBASE Group is preparing to launch a Raspberry Pi Compute Module 4 carrier with a difference: It can accept two Compute Module 4 boards at once.

    Designed alongside the company’s more traditional ModBerry 500-CM4 and AI Gateway 9500-CM4 products, which adapt the Raspberry Pi Compute Module 4 system-on-module family for industrial use, the ClusBerry CM4 is a very different beast. “[The] main difference between standard Gateway and ClusBerry is the possibility to include multiple Compute Module 4 [boards] in one device,” the company explains, “as well as the intended suitable amount of wired and wireless interfaces, suited for the project.”

    The Raspberry Pi Foundation reveals details on its next single-board computers, including PCIe support

    The Pi Foundation has multiple products in development, including a Pi 4A.

    Apparently, the Pi Foundation has the Raspberry Pi 4A and Raspberry Pi 5 in the pipeline, along with new a Raspberry Pi touchscreen display.

    Upton adds that the Pi 4A would have arrived by now, but for the ongoing semiconductor shortage. Instead, the Pi Foundation has been using the SoCs that it has available for the three Raspberry Pi 4 variants that are already available. Supposedly, the Pi Foundation is toying with the idea of doing without USB 3.0 ports on the Pi 4A. According to Tom’s Hardware, losing USB 3.0 ports would allow it to include PCIe connectivity, which the Compute Module 4 already supports. Another cost-saving and space saving option would be to swap the two mini HDMI ports in the Raspberry Pi 4 Model B with a full-size HDMI port.

    Tom’s Hardware suggests that the Pi 4A could arrive in 2022, possibly alongside an updated Raspberry Pi touchscreen.

    Pi Server Project Can Survive Power Outages, Looks Awesome

    A Pi with a UPS in an excellent case

    The guts of the server is a Raspberry Pi 4 with a 32gb Micro SD card and cooled by a low-profile Ice Tower fan and heatsink. The UPS is via a module from GeeekPi via AliExpress, and is filled with a pair of Kiminors 18650 3.7V 2600mAh Li-ion rechargeable batteries. The UPS acts as a HAT on the Pi, but actually fits beneath it, making contact with the bottom of the GPIO pins via some spring-loaded pogo pin contacts. Klements was able to run the box for an hour and a half from a fully charged set of batteries.

    The OLED display has a resolution of 128 x 64 px and is attached to more GPIO pins and communicates through the I2C interface. Information, such as the status of the UPS batteries, IP address and CPU is displayed on the OLED. The whole project is powered using the Pi’s USB-C connector.

    Pi CM4 on a (TV) Stick

    This Raspberry Pi Compute Module 4 carrier plugs directly into an HDMI port.

    The high computing performance of the Raspberry Pi 4 combined with its native HDMI output makes it a perfect choice for applications involving a television. They have become a favorite among Kodi and RetroPie users. However, the form factor does make them slightly inconvenient to hide behind a TV! A carrier board designed by MBS solves that issue by turning a Pi CM4 into an all-in-one TV Stick.

    - HDMI plug
    - micro SD card connector
    - USB-C connector
    - Two USB2.0 USB-A connectors
    - IR receiver
    - User button (also acts as boot select for eMMC flashing)
    - USB multiplexer selector switch: enable 2xUSB-A ports or CM4 USB device mode
