Open Hardware/Modding: HealthyPi, RISC-V, and More

Linux Gizmos ☛ RISC-V-based ESP32-P4 handheld integrates AMOLED display and LoRa

Measuring about 63 × 109 × 22 mm, the T-Display P4 is built around the ESP32-P4, which combines a dual-core RISC-V CPU running at up to 360–400 MHz with an additional low-power RISC-V core operating at 40 MHz.

Linux Gizmos ☛ HealthyPi 6 provides open-source biosignal acquisition for research and education

The platform is built around a tri-core processing architecture. The main controller is STMicroelectronics’ STM32H757, combining an Arm Cortex-M7 core running at up to 480 MHz with a Cortex-M4 core at 240 MHz for real-time signal processing tasks.

Linux Gizmos ☛ Jetson Thor industrial PC pairs 25GbE networking with optional GMSL2 camera support

The platform is based on the NVIDIA Jetson T5000 module, which is specified to deliver up to 2070 TFLOPS of AI performance using FP4 sparse precision. The module integrates 128GB of 256-bit LPDDR5X memory with a quoted bandwidth of 273GB/s, enabling support for large models, multi-camera pipelines, and sensor fusion workloads.

PC World ☛ Your monitor's USB ports are hiding secret powers

By using the monitor as a central USB hub, you can shorten cable runs, organize devices efficiently, and increase accessibility. High-quality mice, mechanical keyboards, or graphics tablets benefit from this, as short, direct connections often provide more stable data transfers and lower latency.

Now the trade off of course for the ESP32 is the higher power draw. The STM32 and the NRF52 can work better for low and ultra low power use cases. The RP2040 is a nice affordable option, though I hadn't realized there is no internal flash.

Chuck Carroll ☛ Resolving I/O Errors on RPI5 with NVMe

I have an NVMe base for my Raspberry Pi 5 and it's been running for a little over a year without any issues. A couple of months ago I switched to Almalinux and noticed that I could SSH into it right after it booted, but around 30-40 minutes after boot, I could ping from another host on my network but could no longer SSH. When I restarted and was directly consoled in, everything was fine until that ~40 minute mark and I started getting a ton of I/O errors. I couldn't even run basic commands like "ls" or "cd". It took me a couple months of off-and-on fiddling to track down the problem.
