Connectors
The primary interconnection is J1, the 41 position board-to-board, header (Hirose p/n DF9A-41P-1V(20);
mates with: Hirose p/n DF9A-41S-1V(20)) on the bottom of the assembly. (Please note that this header is
common between the OEM200 and OEM100).
Optionally, power can be brought to the board through J3, a two position, right angle wire to board, header
(JST p/n S2B-PH-K-S, mate: JST p/n PHR-2). Here is a schematic drawing of J1 and a list of signal
