PMW3360 optical mouse sensor breakout board, support both 3.3V and 1.8V logic
A dual channel brushless motor controller based on the RP2040 microcontroller, designed in Kicad.
All the sources (Schematics, PCB, VHDL, BIOS sources) for the M8SBC-486. This project is a 486 Homebrew computer, with some efforts to make it kinda PC compatible
Open Source, easy to use Ethernet connected stepper motor controller. Built in FreeCAD, KiCAD and Arduino.
a wireless-only split keyboard based on the chocofi
An open source breakout board for PixArt PAW3395DM-T6QU / PAW3950DM-T5QU low power optical mouse sensor.
A modular device designed to test electrical cables. It supports testing of both short cables (both ends accessible) and long cables (with ends far apart). The device visually indicates conductor continuity using LEDs.
A DC-DC buck converter based on an STM32 Nucleo board
A portable UV exposure controller firmware. The project uses a modular architecture with persistent settings, preset storage in Flash, battery protection logic, and an encoder-driven OLED UI.
