This is a Bluepill-compatible devboard for the STM32F103C8T6 microcontroller. It uses all through-hole parts except for the STM32F103C8T6/STM32F103CBT6 microcontroller and is intended to be an alternative to the Bluepill that is easier to assemble should the Bluepill not be available or suitable. It is somewhat optimized to be RFI resistant given it is a two-layer board This material is copyrighted by Daniel Marks (KW4TI) and licensed under the Creative Commons License CC-BY-SA 4.0.
