ADH-tech GP3906-TLP Data Sheet Rev.A01 3.3V ± 5% DC power supply input. GND (Pin3, Pin8, Pin11,20) The ground of the module. VBACKUP (Pin4) This is the backup power for GPS chipset to keep RTC running when main power is removed. For normal operation, the input voltage must be kept from 2.0V to 4.3V. 3D_FIX (Pin5) The fix flag output. If not used, keep this pin floating and do not put this pin in high level when the module starting up.
ADH-tech GP3906-TLP Data Sheet Rev.A01 1PPS (Pin12) 1 pulse-per-second GPS time reference output RESET (Pin13) With a low level, it causes the module to reset. If not used, keep floating.
