Minimal: common questions

What microcontroller does the Minimal use?

The Minimal is built around the CH552G, from the WCH CH32/CH55x family.

How big is the Minimal PCB?

The Minimal has 2 copper layers and is 1.6 mm thick.

How many components are on the Minimal?

12 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Minimal design files?

From the nicola-strappazzon/CH552 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Minimal design in my own project?

Yes, under the terms of its LGPL-2.1 license, which nicola-strappazzon chose for the repository.

Can I test firmware for the Minimal 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.
