n VCC_IN (DC 3.3V@ 5% power Input)

This is the DC power supply input pin for GPS system. It provides voltage to module.
The power supply must add bypass capacitor (10uF and 1uF). It can reduce the Noise
from power supply and increase power stability.

If shutdown the REB-1315S5 module, please remove the VCC_IN Pin voltage into
Hibernate mode.(It’s will keep the Warm start and Hot start function work well)

n GND

GND provides the reference ground.

n RXA

This is the main receiver channel and is used to receive software commands to the
board from SIRFdemo software or from user written software.

n TXA

This is the main transmitting channel and is used to output navigation and measurement
data to SiRFdemo or user written software.

REB-1315S5 Operational Manual

n RF_IN

Connecting to the antenna has to be routed on the PCB. The transmission line
must to be control impedance from RF_IN pin to the antenna or antenna
connector of your choice. (Impedance 50Ω)

Can be used for active antennas or passive antenna.

Active Antenna Gain Selection: 15 ~ 20dB
We recommend using active antennas, because the active antenna actual test better than the
passive antenna..

n VCC_RF_OUT

This pin can provide maximum power 30mA@3.3V for active antenna.

n 1PPS (TIMEMARK)

This pin provides one pulse-per-second output from the board, which is synchronized to
GPS time. Need firmware supported. If don’t used, can open.

n VRTC_3V3 (Backup battery)

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.
Typical current draw is 50uA.
The supply voltage should be between 2.2V and 3.3V.
