GPS Receiver Board

The GPS Receiver Board is a high-quality GPS module with a built in antenna. It can track up to 22 satellites on 66 channels and has an excellent high-sensitivity receiver. The modules is based on the popular XBeeTM form factor.

The board has Embedded Artists' standard 14-pos expansion connector, and communicates with the GPS-module via the UART interface. Several of our boards have the serial expansion connector on-board. More modules are found here.




The GPS Receiver Board has many advanced features and a packed specification list:

  • Based on PA6H module that includes the MTK3339 chipset
  • Built-in ceramic patch antenna (15 x 15 x 4 mm)
  • -165 dBm sensitivity, up to 10 Hz update rate
  • Track up to 22 satellites on 66 channels
  • Only 20mA current draw during navigation
  • RTC battery-compatible (CR1220 battery connector, note: battery not included)
  • PPS output on fix
  • Fix status LED (0.5Hz blink=no fix, 2Hz blink=fixed position)
  • 3.3V interface via 14-pos (50 mil pitch) 14-pos expansion connector (note: 50-mil pitch cable not included, see Related Products below) or
  • interface module via XBee compatible edge pin lists (note: pin lists included but requires soldering)
  • Auto switchover to external antenna (note that UF.L. antenna connector not included)

Technical details about the PA6H module:

  • Satellites: 22 tracking, 66 searching
  • Update rate: 1 to 10 Hz, 1 Hz default
  • Position Accuracy: 1.8 meters
  • Velocity Accuracy: 0.1 meters/s
  • Warm/cold start: 34 seconds
  • Acquisition sensitivity: -145 dBm
  • Tracking sensitivity: -165 dBm
  • MTK3339 Operating current: 25mA tracking, 20 mA current draw during navigation
  • Output: NMEA 0183, 9600 baud (8N1) default
  • Jammer detection and reduction
  • Multi-path detection and compensation
