What boards using the CH341A are built for

CH341A: common questions

Where can I find a CH341A reference design?

Each of the 3 boards on this page is a real design using the CH341A. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.

Which microcontrollers do boards using the CH341A use?

Most are built on PIC (2).

How big is a typical board using the CH341A?

The median is 254 × 134.1 mm, and 100% are two-layer designs.

What is the most popular open source board using the CH341A?

By GitHub stars, S100 B1FU by CatspersCoffee, with 0 stars.

Can I simulate one of these boards using the CH341A 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.
