Position the mainboard as shown: component side facing up, with the two adjacent connectors along the top edge. “Left” and “right” below refer to this orientation.

Step 1: Connect USB

Locate the connector labeled USB on the mapping daughterboard. Connect it with a ribbon cable to the left-side mainboard connector (FPC1).
