The V2 batch of the ProGCC contains a few errors:

1. The board is too thick (We ordered 1.15mm and got 1.35mm)
2. The programming headers were soldered onto the board by accident

Solutions:

1. Shave down the top of the USB-C opening in the midframe of the controller's shell by roughly .5mm
2. Removing the headers with a soldering iron (Either one by one or the entire piece at once)



Examples:

Removing Headers

Tip: You can slide the black collar piece of the headers off in order to desolder one header at a time, making the process easier.
