Open-source boards designed in KiCad by TheKingOfChaos on GitHub, from 2 repositories. A board’s address here is its repository’s there.
TheKingOfChaos/Console-Server
48 RS-232 console ports on one Raspberry Pi: three identical boards, 16 ports each. Built from the design record of 2026-10-10. KiCad 10.0.7. This is Rev B (git tag rev-A is the first board).
TheKingOfChaos/RF-Power-Monitor
A 2-layer carrier board for the WIZnet W5500-EVB-Pico-PoE. It is 80 x 51.5 mm: exactly as long as the module, so both short edges line up with the module.
