Anyone bulding the gen2 be careful ordering parts from other than mouser.com
since this was backordered on mouser i ordered it from digikey and the holes don't line up.
The space between the 9 pins and 5 pins is not wide enough. The part number is the same but the board is not blue it's black, I didn't think that would matter.
My bad. upon further looking at digikey web page They do have the blue board needed. I just picked the wrong one and didn’t do enough research. sorry for the misinformation
