This is an GPS expansion board designed specifically for the both the version 1 and version 2 Raspberry Pi+ Models (This board is NOT compatible with the original Raspberry Pi A and B boards). This board is designed for applications that use a GPS connected via the serial ports to the Raspberry Pi such as timing applications or general applications that require GPS information. To facilitate PPS the time pulse output is connected to GPIO5 so you can utilise this board to give NTP PPS discipline. This board is equipped with the latest Ublox NEO-6M/NEO-M8N positioning module.
Features:
- 161dBm sensitivity, Update rate up to 5Hz, 50 channels (NEO-6M); Only 30mA current draw (NEO-6M)
- Single GNSS update rate up to 18Hz, Concureent GNSS update rate up to 10hz, 72 channels support NASS, BEIDOU2, SBAS(NEO-M8N)
- Built in Real Time Clock (RTC) - XH414H-IV01E backup battery for more of time keeping even if the Pi is off!
- PPS output on fix, by default connected to pinGPIO5.
- Internal patch antenna which works quite well when used outdoors + u.FL connector and SMA connector for external active antenna for when used indoors or in locations without a clear sky view.
- Fix status LED blinks to let you know when the GPS has determined the current coordinate.
