Ch552g dev board
About the Ch552g dev board
Ch552g dev board is an open source WCH CH32/CH55x PCB design by blueOkiris, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 55.9 × 50.8 mm, with 9 components from 6 distinct parts.
Its main chip is the CH552G, from the WCH CH32/CH55x family. By type, the board carries 2 capacitors and 1 IC.
It belongs with the dev boards & breakouts designs in this gallery.
From the project
A simple breakout board with minimal hardware design for the CH552g
A simple breakout board with minimal hardware design for the CH552g as well as a C project to be used as a basis.
I've become fond of the CH552g for projects as it's simple like AVR unlike something like ARM, but it doesn't require a programmer and has built-in USB support from the factory, unlike something like AVR but like ARM.
To ensure I don't have to constantly order pcb after pcb, I've created this dev board that can go on a breadboard, so I can prototype with the chip more easily.

Ch552g dev board: common questions
What microcontroller does the Ch552g dev board use?
The Ch552g dev board is built around the CH552G, from the WCH CH32/CH55x family.
How big is the Ch552g dev board?
The Ch552g dev board measures 55.9 × 50.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Ch552g dev board?
9 components, from 6 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Ch552g dev board design files?
From the blueOkiris/ch552g-dev-board repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Ch552g dev board design in my own project?
Yes, under the terms of its GPL-3.0 license, which blueOkiris chose for the repository.
Can I test firmware for the Ch552g dev board 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.
