Wii mainboard: common questions

What microcontroller does the Wii mainboard use?

The Wii mainboard is built around the RP2040, from the RP2040/RP2350 family.

How big is the Wii mainboard PCB?

The Wii mainboard measures 55.4 × 34.5 mm, has 2 copper layers and is 1 mm thick.

How many components are on the Wii mainboard?

31 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Wii mainboard design files?

From the xtreme8000/picoAVE repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Wii mainboard design in my own project?

Yes, under the terms of its GPL-3.0 license, which xtreme8000 chose for the repository.

Can I test firmware for the Wii mainboard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
