Adafruit’s PioMatter library adds HUB75 RGB LED Matrix support to the Raspberry Pi 5

The Raspberry Pi 5 brought a more powerful CPU and GPU and faster I/Os compared to the Raspberry Pi 4, as well as some incompatibilities. While the transition from a Raspberry Pi 4 to a Raspberry Pi 5 is usually painless for most applications, Adafruit notes that the ability to drive HUB75 RGB LED matrices was lost on the Raspberry Pi 5 which now relies on the Raspberry Pi RP1 peripheral control to drive GPIOs instead of the Broadcom processor directly controlling them. The company has now addressed that by using the PIO (Programmable I/O) block in the RP1 chip, yes that’s the same PIOs as found in the RP2040 or RP2350 microcontroller, to drive HUB75 RGB LED matrices from the Raspberry Pi 5, and their work can be found on the Adafruit-Blinka-Raspberry-Pi5-Piomatter repository on GitHub. The instructions to install the Adafruit Blinka Raspberry Pi 5 PioMatter library (or just […]

Build a four-wheel RC car with ESP32-CAM board and off-the-shelf parts

ESP32 CAM robot car with off-the-shelf parts

While there are plenty of ESP32-based wireless-controlled robot cars with a built-in camera, like the PiCar-X 2.0 or Zeus Car, it might be more fun and rewarding to build something yourself. That’s exactly what Matt Sroufe did by building his own RC car using off-the-shelf parts and an ESP32-CAM board and writing firmware for it. To get started with the build, you’ll need six main components: A 4-wheel car chassis – $47.49 on AliExpress Electronic speed controller – $5.27 on AliExpress. Matt selected the 30A version with green PCB. Dual-battery holder for about $2 on AliExpress 2x 18650 3.6V cells or 7.4V batteries purchased locally ESP32-CAM board with an external antenna and the 160° FoV camera – About $14 with board, camera, and external antenna. Bluetooth gamepad such as a PS4 controller The total should be around $80 with the batteries assuming you already own a Bluetooth gamepad. You’ll need […]

FlashMyPico – Raspberry Pi Pico / Pico 2 code editing and firmware flashing from a web browser

FlashMyPico website allows you to write C code, build the firmware, and flash it to your Raspberry Pi Pico, Pico W, Pico 2, or Pico 2 W directly from a web browser instead of having to check out the code from GitHub, build it in a terminal, and then manually copy the resulting binary. I’ve given it a quick with a Raspberry Pi Pico 2 board. The first step is to head over to flashmypico.com from your computer or even an Android smartphone. You’ll need a web browser that supports WebUSB, so for example, Firefox is not an option, and I eventually had to use Google Chrome instead. There’s a detect device link on the bottom left, so I clicked on that first, and my Raspberry Pi Pico 2 was detected as “RP2350 Boot” after I put it in bootloader mode. But it just told me that my board is […]

GEEKOM A6 Review – Part 2: A sub-$500 mid-range AMD Ryzen 7 6800H mini PC tested with Windows 11 Pro (Sponsored)

In the first part of the review, we’ve already checked out the specs, gone through an unboxing and a teardown of the GEEKOM A6 mini PC powered by an AMD Ryzen 7 6800H CPU with up to 32GB DDR5 and a 1TB SSD, before quickly booting the preinstalled Windows 11 Pro. We’ve now had time to test the GEEKOM A6 in detail, so we’ll report our experience with the Ryzen 7 6800H mini PC with Windows 11 Pro. We’ve tested the features, ran benchmarks, evaluated storage and networking performance, stress-tested the device to see how it performs under load, and measured fan noise and power consumption. We’ll also compare it to the previous GEEKOM A5 and A7 mini PCs. [Update: The sponsored tag was added temporarily, as GEEKOM paid for the review to be pinned at the top of the website for one week] Software Overview and Feature Testing Going […]

DeepSeek shown to run on Rockchip RK3588 with AI acceleration at about 15 tokens/s

Rockchip RK3588 DeepSeek R1 NPU acceleration

DeepSeek R1 model was released a few weeks ago and Brian Roemmele claimed to run it locally on a Raspberry Pi at 200 tokens per second promising to release a Raspberry Pi image “as soon as all tests are complete”. He further explains the Raspberry Pi 5 had a few HATs including a Hailo AI accelerator, but that’s about all the information we have so far, and I assume he used the distilled model with 1.5 billion parameters. Jeff Geerling did his own tests with DeepSeek-R1 (Qwen 14B), but that was only on the CPU at 1.4 token/s, and he later installed an AMD W7700 graphics card on it for better performance. Other people made TinyZero models based on DeepSeekR1 optimized for Raspberry Pi, but that’s specific to countdown and multiplication tasks and still runs on the CPU only. So I was happy to finally see Radxa release instructions to […]
