CH32V Series Open-Source Hardware Boards
WCH CH32V RISC-V development boards plus the WCH-LinkW Bluetooth debug probe — schematics, PCB and BOM fully open-source (MIT), ready for your own PCBA production.
Why we open-source
open-riscv.com is a RISC-V developer community at heart. Open-sourcing these boards means:
- Anyone can learn from, modify, and mass-produce their own derivatives
- Design issues are found and fixed faster by the community
- Lower the barrier for everyone to start building with RISC-V MCUs
License: MIT. Please keep the "open-riscv" attribution (silkscreen) in derivatives.
