Slimline PCB to supply power to trimmed Wii motherboards

Features

• Solders directly onto the top of a Wii motherboard
• Supplies power to the 1V, 1.15V, 1.8V, and 3.3V points
• Power connector allows for modular builds without soldering/desoldering wires
• Adds pads for the relocation of capacitors (C5, C189, C200) typically removed on more aggressive trims
• Pad for an optional thermistor, for compatibility with 4Layer Technologies RVL-PMS
• Fits entirely within the outline of an Omega trim
• Fits under heatplates/heatsinks

Parts / Ordering

• Grab the Gerber files for the latest release
• Order a 2-layer, 0.6mm PCB from JLCPCB or similar fab
• Purchase a 6-pin Molex Pico-Lock connector, PN 504050-0691 (DigiKey, Mouser)
• Purchase either a pre-assembled cable, or parts to crimp your own
  • 50mm pre-assembled cable, PN 15132-0600 (DigiKey, Mouser)
  • 100mm pre-assembled cable, PN 15132-0601 (DigiKey, Mouser)
  • Connector, PN 504051-0601 (DigiKey, Mouser)
  • Crimp terminals, PN 504052-0098 (DigiKey, Mouser)
• Optional - 10KΩ thermistor with a 3380K B value, in an 0603 SMD package

Installation

• If you are doing a motherboard trim that will trim off C5 or C189, desolder these and save them
• If you are doing a NAND relocation which removes C200, desolder this and save it
• Solder the connector and any rescued capacitors to the board by hand or using a hot plate
• Place board on the Wii motherboard, it should self-align
• Solder the pads on the edge of the board to the Wii motherboard
  • 1V0 to the top of C143
  • 1V15 to the left of C17
  • 1V8 to the via array at the top left. You may wish to scratch away some solder mask to have more copper to solder to.
  • 3V3 to the top of C128
  • GND to the bottom of C180 and C143
• Use plenty of solder and flux!

C189 height

Some motherboard revisions have a very tall (~2.9mm) C189 capacitor, which can interfere with heatplates if you are relocating it. If you have one of these boards, you may wish to consider purchasing a lower profile capacitor. As long as it is a 220uF, 6.3V+, 2917 or 2312 SMD package capacitor it should work fine. The Kyocera AVX NOJY227M006RWJ is a low profile version of the original cap used on the Wii. The TAJX227K006RNJ or TAJY227K006RNJ should also both work.

RVL-PMS Companion Board

If you want to use Power Strip with the 4Layer Technologies RVL-PMS-2, or RVL-PMS-Lite boards, Y2K has kindly designed a carrier board called the Power Strip PMS Companion, which is included in this repository for convenience.

You can read more about it in the pms-companion directory.
