Wiring question: AliExpress USB-C board
Hi, I have one of those AliExpress USB-C boards lying around and a Game Gear that still uses AA batteries. I know these boards are not the best option, but it's what I've got. The only issue is, I can't seem to find any instructions for them. The board is marked '2S,' which would suggest you need to wire the batteries in series, but it also has two separate pairs of terminals to solder the batteries to. So, how is this supposed to be wired up? I don't want to fry anything on the Game Gear.
