About the Ch32v00x promicro PCB

Ch32v00x promicro is an open source RISC-V PCB design by 74th, published on GitHub under the MIT license. It is a 2-layer board measuring 17.8 × 33 mm, with 17 components from 15 distinct parts.

Its main chip is the CH32V003F4P6, from the RISC-V family. Other key parts include the AMS1117-3.3 and CH213K. By type, the board carries 5 connectors, 3 ICs, 3 capacitors, 3 resistors, 1 jumper and 1 switch.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

I forked the CH32V003 ProMicro v1.3.0 to simplify it by removing the USB wiring.

CH32V003 ProMicro v1.3.0から、USBへの配線を取り除いてシンプルにするために、forkしました。

- ProMicro size - To replicate the ProMicro, the CH32V003 lacks sufficient GPIOs, so PC1 is connected to both pin 5 (2/SDA) and pin 13 (10/A10). - The MCU's VCC is set to 3.3V, but can be switched to 5V by connecting JP1 and removing the U2 3.3V regulator. - The oscillator used is the MCU's built-in oscillator.

Ch32v00x promicro: common questions

What microcontroller does the Ch32v00x promicro use?

The Ch32v00x promicro is built around the CH32V003F4P6, from the RISC-V family.

How big is the Ch32v00x promicro PCB?

The Ch32v00x promicro measures 17.8 × 33 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ch32v00x promicro?

17 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Ch32v00x promicro design files?

From the 74th/ch32v-dev-boards repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Ch32v00x promicro design in my own project?

Yes, under the terms of its MIT license, which 74th chose for the repository.

Can I test firmware for the Ch32v00x promicro 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.
