README
README.mdSTM32C071G8 Development Board
This repository contains a tiny STM32C071G8U6N development board developed in KiCAD8. The board took just 1 day to develop and another few hours sorting out some JLCPCB issues (wrong/shifted part alignments, selecting parts from LCSC etc).
Note this board has not yet been manufacturered (JLCPCB gave a quote for £47{UK} for 5 Boards).
The boards is nothing more but a USB-C connector, STM32C071 and a 3.3v power regulator. Schematics/PBC/Manufacturing data is located in the KiCAD directory.

Questions
How big is the STM32C071 Dev Board PCB?
It measures 38.4 × 19.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the STM32C071 Dev Board use?
24 parts, built around the TPS73633DBV and SP0503BAHTG. 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.
Where can I download the STM32C071 Dev Board KiCad files?
From the htminuslab/STM32C071_Dev_Board repository on GitHub, at the commit this page was made from: the board is KiCAD/stm32c071devboard.kicad_pcb and its schematic KiCAD/stm32c071devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32C071 Dev Board design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
