The goal of this project was to create a smaller version of the Wii with minimal cost and labor that I can use for smash tournaments. This was heavily inspired by @Gman so shout outs to him for doing it first. The BOM for this build was $60. It is powered by USB C and a custom regulator board similar to powermii but without the 5v regulator to decrease cost. It maintains the four controller ports/video out on the Wii. No glue was used in the making of this project--Everything is held in by screws.

EDIT: Updated this post with version 2. Enjoy!

Nice. You should print some graphics for the top too so it's not so plain, and counter-sink those screws!

It's just a simple breakout. You can get 5V 3A from USB C by connecting a 5.1k pull-down on each CC line. Also just put a 100uF cap on there to stabilize the input.

Don't always assume you can get all 3 amps though, usb c to usb a can't magically create power if you plug it into a 5v 1a block

You just need a 5.1k pulldown resistor on each CC pin on the port. It shouldn't matter what USB C brick/cable you use as long as you're not using a USB C to A converter cable. This is because USB C provides a minimum of 5v 3A which is suitable for powering a Wii.

Is there a guide with the bom?

If are interested in making your own it is relatively simple. I perform the OMGWTF trim but retain the USB port, AV out port, and the fourth screwhole. You need some regulators, in this case I designed a powermii lite clone but without the 5v regulator since I chose to power from USB C. If you choose to use micro USB or USB C the 5v regulator is not necessary but you will need to remove the preamp since it doesn't work well on 5v. Basically the only wiring necessary is the regulators, controller ports, and power switch. As for the case, that's up to you based on how you want to implement it.

There is no guide available. Most of the time 3d models aren'd shared. The BOM somewhere else on the site.

Do you have any idea where I could find a BOM? Thanks.
