Pin Map of J2 Board to Board Connector.
※ B-to-B Connector mating should be enhanced with additional Locking method.
(T-200 has two of screw type-locking hole - 2Ø U-type hole)
※ T-200 has B-TO-B connecting PLUG (Molex: 55560-0168) on PCB. And mating B-TO-B
Receptacle (Molex: 54722-0164) should be on Main PCB. Mating Receptacle with PLUG should
be done very carefully. Only the gripping of side plane of T-200 is allowed while as pressing on
Top plane or Bottom of T-200 is strictly restricted.
