Description

BerryGPS-IMU has been specifically designed for the Raspberry Pi Zero. It is also compatible with all other versions Raspberry Pi.

BerryGPS-IMU is a GPS module which also includes all the sensors found in the BerryIMU.

The sensors found on the BerryGPS-IMU are:

  1. GPS 
  2. Accelerometer
  3. Gyroscope
  4. Magnetometer (Compass)
  5. Barometric/altitude
  6. Temperature

GPS

BerryGPS-IMU uses the M10478-A2 from Antenova, which is a high quality GPS module which is able to track 22 satellites.

Built in antenna:  BerryGPS-IMU comes with an inbuilt 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 indicator:  The fix LED will flash once a second when a fix has been obtained. The fix signal is also presented on an output pin.

PPS: BerryGPS-IMU also includes Pulse Per Second(PPS) functionality.  With a LED which will flash on every pulse and an output pin to be used by a microcontroller for time syncing.

Standby Pin: Include and pin to place the GPS module into standby mode.

Periodic mode: Periodic mode is a module controlled mode that reduces current consumption by only waking the module for short periods to maintain fix data.

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

An external antenna can be found here.

GPS Antenna
28dB active antenna

This external antenna increases the signal via 28dB.

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  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 is compatible will all models of Raspberry Pi, including Pi 2, Pi 3 and Zero.
