This repo contains the KiCad hardware design files for a development board for the STM32F103 MCU, which is somewhat similar to the well known blue pill board. The design(er) has greatly benefitted from some of Phil Salmony's designs 🙏.
- STM32F103 MCU
- 2x I2C (pull up resistors included)
- SPI (22R series termination resistor included)
- USB micro
- UART
- 21 GPIOs
- 16MHz crystal
- ESD protection
- SWD via legged 6-pin plug-of-nails tag-connect connector
- BOOT0 pin toggle switch
- NRST pin push button
- Power LED
- LDO voltage regulator
All files necessary for manufacturing the board at the pcb manufacturer of your choice can be found in ./manufacturing_r0.1. This includes the drill files, gerbers, bill of materials and a basic assembly drawing.
Fully manufactured version of the board:
