About the CH32-devBoard PCB

CH32-devBoard is an open source WCH CH32/CH55x PCB design by parammakersadda, published on GitHub under the CERN-OHL-W-2.0 license. It is a 2-layer board measuring 40.5 × 45.5 mm, with 15 components from 10 distinct parts.

Its main chip is the TSSOP-20_4.4x6.5mm_P0.65mm, from the WCH CH32/CH55x family. By type, the board carries 5 connectors, 5 resistors, 2 diodes, 1 IC, 1 switch and 1 capacitor.

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

From the project

a simple development board based on CH32X033F8P6 microcontroller

This project was developed by Param Makers Adda to provide an open hardware development board based on the CH32X033F8P6 microcontroller. The design is intended to be studied, modified, manufactured, and improved by anyone under the terms of the CERN Open Hardware Licence Version 2 – Weakly Reciprocal (CERN-OHL-W v2).

CH32-devBoard: common questions

What microcontroller does the CH32-devBoard use?

The CH32-devBoard is built around the TSSOP-20_4.4x6.5mm_P0.65mm, from the WCH CH32/CH55x family.

How big is the CH32-devBoard PCB?

The CH32-devBoard measures 40.5 × 45.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CH32-devBoard?

15 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the CH32-devBoard design files?

From the parammakersadda/CH32-devBoard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the CH32-devBoard design in my own project?

Yes, under the terms of its CERN-OHL-W-2.0 license, which parammakersadda chose for the repository.

Can I test firmware for the CH32-devBoard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug WCH CH32/CH55x firmware against it before you order a PCB.
