README
README.mdSTM32 Dev Board
This is a simple STM32 development board that I designed for my own use. It is based on the STM32F103C8T6 microcontroller. The design is inspired by the Blue Pill development board.
Manufacturing
The board is designed to be manufactured using the JLCPCB assembly service. All the files required for manufacturing are in the manufacturing directory.
Mechanical
The board is designed to be mounted in a 3D printed case. The case files are in the case directory or can be found on Printables and Thingiverse.
The dimensions of the board are (L x W x H) 64mm x 24mm x 1.6mm.
The mounting holes are designed for M2 ISO7380 screws.

Questions
How big is the Dev board PCB?
It measures 64 × 24 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dev board use?
43 parts, built around the AMS1117-3.3 and USBLC6-2SC6. 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 Dev board KiCad files?
From the chari-md/dev_board repository on GitHub, at the commit this page was made from: the board is dev_board.kicad_pcb and its schematic dev_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dev board design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
