I messaged the seller, according to him it'll work just fine. I'd of course rather have one with clearly labelled support but haven't had any luck finding it.
it is joined as 12 pin, but (see image) it seems like only 4 traces are actually data, 4 more are not connected an the rest seem tied together to ground or power. This makes me a bit worried. I was hoping this was just some standard that I could easily find a connector for. Because I really don't have the equipment to solder that small.
