OzzMaker BerryGPS-IMU V4 for Raspberry Pi

BerryGPS-IMU V4 has been designed to fit perfectly with the Raspberry Pi Zero. It is also compatible with all other versions of the Raspberry Pi and Arduino.

Included Sensors

• GPS
• Accelerometer
• Gyroscope
• Magnetometer (Compass)
• Barometric/Altitude
• Temperature

BerryGPS-IMU V4 uses the CAM-M8 from uBlox, which is an advanced high quality GPS module.

3 concurrent GNSS: Concurrent reception of up to 3 GNSS (GPS, Galileo, GLONASS, BeiDou)

Embedded Antenna: Embedded, omnidirectional and wideband antenna

Super Cap: The SuperCap keeps the ephemeris data stored in the battery backup RAM for 2 hours.  This allows for faster acquisitions when the module is power cycled.

Fix and PPS indicator: The on board LED will flash once a second when a fix has been obtained. The PPS signal is also presented on an output pin.

Time Pulse Output (PPS): 0,25Hz - 10MHz (default 1Hz)

Protocols: NMEA, UBX binary, RTCM

Update Rate: Single GNSS - up to 18Hz, Dual GNSS up to 10Hz

Connection for external antenna: BerryGPS-IMU v4 also includes a uFL connector for an external antenna, which can be used when BerryGPS-IMU v4 doesn't have clear access to the sky.

u-Center: A graphical interface to test and configure the  GPS module on the BerryGPS-IMU
