BerryGPS-IMU v2 Plate has been designed to fit perfectly with the Raspberry Pi Zero. It is also compatible with all other versions Raspberry Pi, including the Pi 3B+.
BerryGPS-IMU v2 uses the M20048 from Antenova, which is a high quality GPS module which is able to track 22 satellites. The BerryGPS-IMU v2 is a GPS module which also includes the sensors that can be found on the BerryIMU v2 Plate.

BerryGPS-IMU v2 is also fitted with a barometric sensor (BMP280) which can be used to calculate altitude. A temperature sensor is also included.

Sensors included are;

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

GPS Module M20048

  • Low current consumption, <200uA when using Periodic mode.

  • UART  4800/9600/38400/115200 bps
  • Channels – 210 PRN / 66 Acquisition / 22 Tracking
  • Max update rate 5 Hz
  • Horizontal position accuracy <2.5m CEP
  • Acquisition sensitivity -148dBm
  • Tracking sensitivity -165dBm
  • Hot start <1s
  • Warm start <25s
  • Cold start <35s
  • Orbit prediction
  • 1PPS Sync
  • Fix LED
  • PPS LED
  • Internal antenna
  • Connector for external antenna
  • SuperCap to help store ephemeris data.

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.

How to build an AirPlay receiver with Raspberry Pi Zero

Raspberry Pi Zero

The number of things you can do with a Raspberry Pi is astounding. For a little over $35, you can create a networked media server for streaming all your digital movies to your TV or give your existing printer wireless capabilities. And that’s just the tip of the iceberg.

If you’ve yet to decide on what you want to do with your Raspberry Pi, this project shows you how to turn it into a Chromecast Audio-like music streamer. This means you could set up several Raspberry Pis this way, connect each one to a speaker, place them around your house and stream music to each those speakers remotely in a highly configurable way. You can control the music from your phone, tablet or computer.
