Interface Functions

  • VCC: 5V power supply
  • RXD: Data in pin of serial port
  • TXD: Data out pin of serial port
  • 1PPS: This pin provides one pulse-per-second output from the board, which is synchronized to GPS time. 200ms active high.
  • VBAT: This is the battery backup input that powers supply the Hibernate mode when main power is removed. It’s will keep the Warm start and Hot start function work well. The supply voltage should be between 2.8V and 3.3V.

Voltage Level

The default voltage level of RXD and TXD pins is 5V, if you need 3.3V level, please remove the 0R resistor on R2, and short out the resistor on R1.
