connector; internally the pin-out is the same of any standard MicroSIM card.
7 SHIELD GND
For ESD protection, on all signal lines are placed clamping diodes for voltage transient
suppression.
8 SHIELD GND
9 SHIELD GND
SHIELD GND Signals related to UIM (SIM) card have already been described in the previous paragraph.
Since Qseven
