Product Description

This GPS receiver comes with embedded antenna and only needs 5 pins to talk to your Arduino or MCU.

Pin  1:  GND Ground   
Pin  2:  VCC Power supply of 3.3 ~ 3.5 VDC
Pin  3:  TX Port A serial data output (GPS out); N-8-1, NMEA v3.00 output
Pin 4:   RX Port A serial data input (GPS in); N-8-1, accepts commands from external applications, e.g. SiRFDemo.
Pin 5:   5 PWR_CTRL Hardware controlled power saving pin.
            If this function is used, it is usually connected to a GPIO pin of a micro-processor.
            "Low": for normal run
            "High" or floating: turn off VCC for power saving
             Tie it to low if this pin is not used.

For Arduino application, we recommend aspen board: 

Not only handheld but also any other GPS applications can share the following major features
of SR-92.

  •  Easy adoption with best performance
  •  Integrated antenna and EMC protection
  •  Built-in backup battery allowing hot/warm starts and better performance
  •  No external component demand, just connect and use.
  •  Minimum RF and EMI efforts
  •  Small size of 18 (W) x 21 (L) x 7 (H) (mm) with patch antenna of 18x18x4mm.
  •  Fully implementation of ultra-high performance SiRFstarIII single chip architecture
  •  High tracking sensitivity of -159dBm
  •  Low power consumption of 40mA at full tracking
  •  Hardware power saving control pin allowing power off GPS via GPIO
  •  SR-92 could be arranged at best reception location inside housing
  •  Firmware upgradeable for future potential performance enhancements



         Download SiRFdemo software that can be used to configure the baud rate, etc

Arduino GPS Tutorial

1. Get some male to male jumper from:

    Cut in the middle.

 2. Solder on the the 5 pins of the GPS receiver module:


3. We will first bypass the MCU, and let GPS directly talk to PC using the USB.

    The schematics is as follows:



For the other three pin, we connect GND to Arduino's GND, VCC to Arduino's V3.3V pin, and the POWER_CTL to Arduino's GND as we want the GPS always tracking for now.

For convient, we used Arduino Protoshield (


4. The Serial terminal we will is is X-CTU from digi.

    The data manual says that the default baud rate is 4800. However, on ours, we found that the default one is 9600.
