Switch microcontroller: common questions

What microcontroller does the Switch microcontroller use?

The Switch microcontroller is built around the CH554P, from the WCH CH32/CH55x family.

How big is the Switch microcontroller PCB?

The Switch microcontroller measures 23 × 34.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Switch microcontroller?

9 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Switch microcontroller design files?

From the Pever3ll/switch-microcontroller repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Switch microcontroller design in my own project?

The repository has no license, so all rights stay with Pever3ll. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Switch microcontroller 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.
