SIM card connectors follow the ISO 7816 contact assignment: C1 = VCC (power), C2 = RST (reset), C3 = CLK (clock), C4 = AUX/NC, C5 = GND (ground), C6 = VPP/NC, C7 = I/O (data), C8 = NC. A 6-pin socket carries the essential contacts (C1, C2, C3, C5, C7 plus one auxiliary), an 8-pin socket exposes all eight, and a 2FF (full-size SIM) socket keeps the same C1-C8 electrical definition in a larger ID-1...
