Ozzmaker BerryGPS-IMU V3
BerryGPS-IMU v3 has been specifically designed for the Raspberry Pi Zero . It is also compatible with all other 40-pin versions of Raspberry Pi.
BerryGPS-IMU v3 is a GPS module which also includes all the sensors found in the BerryIMU v2.
The sensors found on the BerryGPS-IMU v3 are:
- Magnetometer (Compass)
BerryGPS-IMU v3 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 onboard 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 v3 also includes a uFL connector for an external antenna , which can be used when BerryGPS-IMU v3 doesn’t have clear access to the sky.
u-Center: A graphical interface to test and configure the GPS module on the BerryGPS-IMU

An inertial measurement unit, or IMU, measures and reports on velocity, orientation and gravitational forces, using a combination of an accelerometer, gyroscope and a magnetometer.
BerryGPS-IMU v3 is also fitted with a barometric sensor (BMP280) which can be used to calculate altitude. A temperature sensor is also included.
IMUs can be found in devices like, quad copters, smart phones, segways, Wii Remote etc.. and are used to sense movement and orientation.
BerryGPS-IMU v3 is compatible will all models of Raspberry Pi, including Pi 2, Pi 3 and Zero.
