20 open source boards using the CH340G
Real designs built with the CH340G, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

What boards using the CH340G are built for
CH340G: common questions
Where can I find a CH340G reference design?
Each of the 20 boards on this page is a real design using the CH340G. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
What parts are used alongside the CH340G?
The AMS1117-3.3, AMS1117-5.0, 23LC1024, BluePill_STM32F103C and LM2596S-5.0 appear in the most repositories here.
Which microcontrollers do boards using the CH340G use?
Most are built on ESP32 (4), AVR/Arduino (3), STM32 (3) and ESP8266 (1).
How big is a typical board using the CH340G?
The median is 77.2 × 62.1 mm, and 60% are two-layer designs.
What is the most popular open source board using the CH340G?
By GitHub stars, 65uino by AndersBNielsen, with 165 stars.
Can I simulate one of these boards using the CH340G before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
