From the project
Open-source CH32V006 RISC-V dev board — KiCad hardware (schematic + PCB), USB-C power, 3.3 V LDO, SWD/CH340C, and a PD1 blink example.
A tiny, open hardware RISC‑V playground.
- MCU: WCH CH32V006 (RISC‑V, 48 MHz class) - USB‑C for power (VBUS) and connectors - On‑board 3.3 V LDO for clean power - SWD header for flashing with WCH‑LinkE - CH340C USB‑UART for serial logging / optional bootloader work - Break‑out headers for all GPIOs (PD0–PD7, PC0–PC7, PA1–PA2, etc.) - Compact 2‑layer PCB with mounting holes

Ch32v006-dev board: common questions
What microcontroller does the Ch32v006-dev board use?
The Ch32v006-dev board is built around the CH32V003FxPx, from the RISC-V family.
How big is the Ch32v006-dev board?
The Ch32v006-dev board measures 25 × 41.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Ch32v006-dev board?
26 components, from 17 distinct parts. The full bill of materials is listed on this page.
Where can I download the Ch32v006-dev board design files?
From the rmingon/ch32v006-dev-board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Ch32v006-dev board design in my own project?
The repository has no license, so all rights stay with rmingon. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Ch32v006-dev board without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
