Chosen Solution
I had purchased a motherboard from eBay at one point, and received a small square. However, I need to replace the entire green board control board, not just a piece of it. Is there anywhere I can purchase the full tablet control board and not just bits and pieces?
It sounds like you must have gotten the board for one of the Joycon controllers. Unfortunately, there is no other place other than eBay where you can find motherboards for these. I don’t see motherboards come up for sale often on eBay but sometimes they do.
