Wii Motherboard Breakout PCB

Wii motherboard breakout board for USB, Bluetooth, GameCube controllers, A/V, and RST lines.

This is designed to be permanently mounted to a (trimmed) Wii motherboard to give access to peripheral data lines without having to worry about breaking small wires. I designed this allow me to rapidly prototype "daughterboard" peripheral PCBs without having to de-solder/re-solder.

Useful for prototyping, or for permanent installation on Wii projects which are mounted with the CPU/GPU facing up (probably not most portables).

Features

• Pads aim to be as close to onboard vias as possible
• Designed to lay flush with 4-layer Wii motherboards
• Cutout for capacitor (C56)
• Can be screw mounted (M2 or M2.5 screws), glued, or soldered
• Castellated mounting holes
• Footprints for vertical JST-SH headers
• Breaks out:
  • USB (D-, D+)
  • Audio (L, R, GND)
  • Component/RGB Video (Y, Pb, Pr, GND)
  • Bluetooth (D1, D2)
  • GameCube Controllers x4 (SI line)
