Basic STM32F042 breakout baord
This is built around the 20pin STM32F042 package.
features :
- Crystal less USB
Note this is a vary basic desing and lacks a lot things needed for somthing to use outside of the lab, like ...
- USB ESD protection
- Polarity protection diode
- BOOT0 tied to ground via a 10k or so resistor
The main goal of this project was to get a working STM32 system with minimal componentss
