README
README.mdSTM32-DevBoard
This is my attempt to create a development board based on the STM32F103C8T6 microcontroller, with both USB-C and up to 12V input through a barrel Jack. The idea is to create this board as a learning exercise and I will expand the design into a sensor fusion board in the future.
Features:
- SWD Programming interface
- UART interface
- I2C interface
- 2 addressable LEDs
- 6 exposed GPIO pins
- USB-C power input
- 12V barrel jack power input
- 5-12V -> 3.3V buck converter
- STM32F103C8T6 microcontroller
Design Decision:
I went with a 12V barrel jack as I wanted to gain some experience with buck converters. In hindsight, this didn't need to be added as the USB-C is perfectly adequate for my use case.

Questions
How big is the STM32-DevBoard PCB?
It measures 55.5 × 45.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the STM32-DevBoard use?
56 parts, built around the STM32F103C8T6, TPS563209DDCR, USBLC6-2SC6 and 12402012E212A. 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 STM32-DevBoard KiCad files?
From the maxai472/STM32-DevBoard repository on GitHub, at the commit this page was made from: the board is STM32-DevBoard.kicad_pcb and its schematic STM32-DevBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32-DevBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask maxai472 before reusing the design.
