AVEflex is my flexible printed circuit board (FPC) for relocating the Audio-Video Encoder (AVE) on 4-layer Wii motherboards. AVEflex is intended for OMEGA trims where analog video is needed and avoids the sacrificial daughterboard method currently used for AVE relocations. Supported motherboard revisions are:
  • RVL-CPU-40
  • RVL-CPU-50
  • RVL-CPU-60
  • RVK-CPU-01
  • RVK-CPU-02

The FPC breaks out all analog signals generated by the AVE: YPbPr/RGBHV, composite video, and stereo line level audio. There’s also a solder jumper for the Wii’s MODE pin, so you can easily connect MODE to 3.3V to enable progressive component or VGA.

Assembly
The AVE is removed from the donor Wii with hot air. The AVE is then hotaired back onto the flex board to connect the thermal pad under the IC. The AVE pins must be drag soldered onto the FPC. I recommend using a tacky flux with a long active time like Chipquik SMD291 or similar. Kester 951 doesn’t really cut it for drag soldering IMO.

3.3V, GND, and 1.8V must be connected to the FPC on the three pads labeled as 3.3, G, and 1.8 respectively. 34 AWG works fine for this.

Passives can either be harvested from the Wii motherboard, or you can use new components. I choose to buy new passives so I don’t have to bother desoldering the originals. You'll need to reference the RVK compendium and JacksonS's component values in Shank's Wii Super Thread for component placement. The FPC requires:
  • x9 0402 0.1uF
  • x1 0402 10nF
  • x1 0603 10uF
  • x1 0603 4.7uF
  • x4 0402 75Ω
  • x1 0402 1.2kΩ.
Here’s my Mouser Project with the BOM.

Note: For this board rev you need to short pins 22 and 23 on the AVE with solder to keep the AVE out of reset. I didn’t connect them on the PCB for testing purposes, but any future runs will have these connected internally.

As the silk message on the underside of the board states, if you’re using a standalone I2S audio amp for your project and don’t need analog audio from the AVE, you can carefully trim off the top 4 pads (marked in white) on the FPC to expose the Wii’s I2S vias, and disconnect the AVE from the I2S bus. If you decide to do this, make sure you do not sever the SCL trace on the underside of the FPC, or the AVE will not be initialized properly.

Please note: This is not a beginner-friendly product. The install is difficult and the FPC is delicate. AVEflex is intended for OMEGA trims and as such I take no responsibility for motherboards or FPCs damaged due to user error. If you want/need a detailed guide on installing or using AVEflex, don't buy one. :P

I have only a few AVEflex FPCs on hand. Cost per unit is $5 plus shipping. Anyone interested in purchasing AVEflex can DM me here on BB or on Discord @YveltalGriffin#8080.

My original stock of AVEflex is nearly gone, and I have no plans to get another batch anytime soon. So I'm releasing the Gerber files for anyone that wants to get these manufactured.

This is a slightly updated design that entirely omits the unecessary POR RC circuit, and connects RESET to 1.8V on the FPC (no pin bridging required.) Most pads/vias are also teardropped to make them sexier (and less prone to delamination). They meet GoldPhoenix's 5/5mil trace/space guidelines.

Enjoy!
