Custom STM32WB microcontroller to practice my PCB schematic and layout skills. Looking to get it printed soon! Bear in mind that this is an ameuter project, so there will probably be errors aplenty.

vexpaer/vexpaers_heart
Open-source Holter ECG recorder hardware: ADS1294R, STM32WB55, microSD, BLE and USB-Pogo dock
It measures 55.5 × 32 mm and has 4 copper layers, 1.62 mm thick.
52 parts, built around the STM32WB55RGV6, DLF162500LT-5028A1, BME280 and MIC5365-3.3YD5-TR. 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 dibreyjonatan/SAFE-ROOM repository on GitHub, at the commit this page was made from: the board is Hardware/Hardware.kicad_pcb and its schematic Hardware/Hardware.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
