About the Stm32c5-bluepill PCB

Stm32c5-bluepill is an open source STM32 PCB design by thomashamain, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 53.3 × 22.9 mm, with 63 components from 34 distinct parts.

Its main chip is the STM32C5xxCx, from the STM32 family. Other key parts include the 3.3V LDO, AP63205WU, TCAN334 and USBLC6-2SC6. By type, the board carries 27 capacitors, 10 resistors, 9 connectors, 6 ICs, 5 diodes and 3 switches.

From the project

Open-source STM32C5 Blue Pill-style board exploring practical compatibility with the classic STM32F103 Blue Pill.

ST released the STM32C5 family, a cost-sensitive Cortex-M33 series with modern peripherals, more memory, and much better headroom than the classic STM32F103 used in the Blue Pill designs. Since the spirit of a bluepill is to be affordable/cheap, compact, have good performances, and be versatile for a large part of diy projects, the C5 could be a perfect evolution for the bluepill.
