This project implements the board recorded in the engineering portfolio: STM32WB55 MCU, USB-C power/data, single-cell LiPo charging, 3.3 V regulation, I2C environmental sensing, external SPI flash and BLE/RF access.



It measures 43 × 20 mm and has 2 copper layers, 1.6 mm thick.
50 parts, built around the ESP32-C3-MINI-1-N4, HX710C, CSD85301Q2 and AP2112K-3.3. 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 itstoomuchbutter/edge_detector repository on GitHub, at the commit this page was made from: the board is edge_detector.kicad_pcb and its schematic edge_detector.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask itstoomuchbutter before reusing the design.
