A small, STM32-pin-compatible development/breakout board built around the CH32V303CBT6 (WCH, RISC-V32, LQFP-48). Footprint and pinout follow the classic "blue pill / black pill" layout used by STM32F103C8T6 boards, so it can be used as a drop-in RISC-V alternative in existing STM32 blue/black pill projects and carriers.
- MCU: CH32V303CBT6, LQFP-48, 7x7 mm, 0.5 mm pitch (custom footprint
LQFP-48_7x7mm_P0.5mm.kicad_modincluded, as it's not in stock KiCad libraries). - 4-layer PCB: top/bottom signal layers plus dedicated GND and 3V3 inner planes.
- Designed in KiCad 9.
