NanoPi R28S – A tiny dual GbE Rockchip RK3528A wireless SBC and router with a USB-C console port

NanoPi R28S is yet another tiny dual Gigabit Ethernet single board computer or router (with a metal enclosure), and the second from FriendlyELEC to implement a USB-C console port, often requested by our readers, after the NanoPi R2S Plus launched in 2024. At just 49.5 x 49.5 x 24 mm in its metal case, the Rockchip RK3528A-powered router also features 1GB LPDDR4, a microSD card slot and an eMMC module socket for storage, WiFi 6 and Bluetooth 5.3 wireless connectivity. The USB-C ports are only used for power, eMMC firmware upgrades, and debugging, and the system doesn’t feature any USB...

reTerminal Sticky 3.97-inch touch ePaper display is supported by four open-source firmware projects (so far)

Seeed Studio’s reTerminal Sticky is a 3.97-inch “AI-powered” magnetic touch ePaper display powered by an ESP32-S3 microcontroller, which serves as a sticky-note alternative, an e-reader, a live dashboard, or a home automation controller. The 800 x 480 resolution display comes with 8MB PSRAM, 32MB Flash, a microSD card slot, and next/previous page buttons. It’s “AI-powered” through a microphone and an AI Voice button leveraging the ESP32-S3 Edge AI capabilities for a voice-to-note feature. It also features a temperature and humidity sensor and a 3-axis accelerometer, as well as a built-in magnet and a magnetic ring for easy mounting. reTerminal Sticky...

Maker Go ESP32-C5-EVB board features RS-485 interface, four relays, four opto-isolated inputs

Maker Go ESP32-C5-EVB is an ESP32-C5 board with four relays, four opto-isolated inputs, RS-485 communication, and support for Wi-Fi 6, Bluetooth Low Energy 5.0, and Thread/Zigbee connectivity. It’s a variant of the Maker Go ESP32-C6-EVB released in 2024 that replaces the ESP32-C6 module with an ESP32-C5 module and a GPIO header with a terminal block for RS-485. The Maker Go ESP32-C6-EVB was mostly a clone of the Olimex ESP32-C6-EVB, and while Olimex already released its own ESP32-C5-EVB, it has a different dual-channel relay design. Maker Go ESP32-C5-EVB specifications: Wireless module – DOIT ESPC5-32 module SoC – Espressif Systems ESP32-C5 CPU...

Name that Ware, July 2026

The Ware for July 2026 is shown below.

I’ve got silicon on the brain, so I’m going to give a die shot another go at name that ware. Hopefully this one is a bit easier than the last one. This excerpt is a design pattern I look for and find on almost every SoC. It’s technically showing a bit more than just the part I’m focused on, so as a hint I’m primarily interested in identifying the structure towards the lower left corner of this image.

If you’ve seen one of these before, you’ll know what it is – it’s pretty unmistakable,...

Winner, Name that Ware June 2026

The Ware for June 2026 is an SGI RM6-64 raster manager, from a KONA/InfiniteReality graphics system. Congrats to Christian for naming it! email me for your prize.

This gem of a board was gifted to me by someone at SGI back when I worked there in…I want to say 1998? I even still have the name plate from my cubicle, from back before the ‘bunnie’ nickname really stuck…

Back then, if you wanted to do graphics, SGI was the only game in town, but I joined the party late. Within six months of joining, most of the division I was in had...

DFRobot seeMote Cube tracks motion and sends haptic feedback in visionOS

The DFRobot seeMote Cube is a handheld spatial input device for Apple Vision Pro application development. The 56mm cube combines six-degree-of-freedom tracking, six programmable buttons, Bluetooth connectivity, and app-controlled haptic feedback for interacting with virtual objects and tools in visionOS. According to the DFRobot, the seeMote Cube provides a tangible controller that can be moved, […]

ESP-KVM – An open-source IP KVM solution based on ESP32-P4 RISC-V MCU

Earlier this month, the P4 KVM project was brought to my attention. It provides IP KVM functionality to a Waveshare ESP32-P4-WIFI6-POE-ETH board when paired with a Toshiba TC358743 HDMI-to-CSI adapter. However, it doesn’t work with the new ESP32-P4 V3.x variants featuring a proper H.264 video encoding implementation, and the developer (Jonathan Rowny) says it’s just a proof-of-concept with many bugs and no security, so I decided to skip it. The good news is that he also encouraged others to fork the project, and Evgenij Spitsyn did just that with the release of the ESP-KVM project, which supports both MJPEG and...

NightRun UEFI application boots a local LLM on Raspberry Pi 5 and x86 PCs without an OS

Running LLMs locally on an SBC or mini PC is a good way to keep your data private, but they typically require a conventional operating system, which uses a good portion of system memory. NightRun is an experimental open-source project that addresses this issue by booting a machine directly into a local LLM from a USB drive or microSD card, without loading a conventional OS. By removing the operating system, NightRun makes more RAM and memory bandwidth available for AI inference. The runtime is written in Rust, and during boot it loads a quantized model (1.3 GB to 2.4 GB)...
