jonaschramm/race-tracker
Custom PCB data logger for motorcycle racing: GPS position + IMU motion data, logged to a microSD card, with an e-Paper status display. Built around an ESP32-S3 (WiFi/BT built in) so it can also stream/sync over WiFi.
It measures 10.2 × 12.7 mm and has 2 copper layers, 1.6 mm thick.
12 parts, built around the BSS138PS. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the mh21/breadboard-adapters repository on GitHub, at the commit this page was made from: the board is serial/serial-breadboard-adapter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
