This project is a compact, open-hardware development board built around the WCH CH32V006 RISC-V MCU. It’s meant to be a friendly entry point for experimenting with WCH’s ultra-low-cost chips while keeping the hardware completely reproducible.

What you get
• Full KiCad project: schematic, 2-layer PCB, and renders
• USB-C power input (VBUS) with on-board 3.3 V LDO
• SWD header for flashing/debugging with WCH-LinkE
• CH340C USB-UART for logs or bootstrapping
• Break-out headers for the MCU GPIOs (PD0–PD7, PC0–PC7, PA1–PA2, …)
• Example firmware: LED blink on PD1
