Super thin split PCB keyboard using rp2040 chips running Rust
Pro Micro/Elite-Pi compatible RP2040 board with USB-C, 8MB flash and up to 25 GPIOs
Semiconductor cosmic radiation detector Silicon diode interface.
Reed switch sensor module for monitoring cabinet and door states over CAN bus
MPTT solar charge controller for 18650 cells.
GNSS positioning module providing location and timing data over CAN bus
Without using a USB-C PD controller chip, handling communication over the USB cable, USB-C standard allows to get 5V up to 3A through a hardware availability detection. Here I show a design developed on KiCad and made through JLCPCB, powering from a USB-PD source and providing 5V and 3.3 (through a step-down converter) up to 3A.
A 2-layer PCB for a small sumobot including MSP430G2553, regulators, motor drivers, and IR receiver.
GNSS-powered, seven-segment table clock
Self-contained 5W Class-D amplifier inside a Speakon connector
Klein keyboard is a 36 keys, columnar staggered, split ergo keyboard
A controller for miniature stepper motors
Microphone Pre-amplifier
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
