Omschrijving
Sensors include are:
- GPS
- Accelerometer
- Gyroscope
- Magnetometer (Compass)
- Barometric/Altitude
- Temperature
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): 0,25 Hz - 10 MHz (default 1 Hz)
-
Protocols: NMEA, UBX binary, RTCM
-
Update Rate: Single GNSS - up to 18 Hz, Dual GNSS up to 10 Hz
-
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

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.

- Measurement range: ±245 / ±500 / ±2000 dps
- Sensitivity: 8.75, 17.50, 70.00 mdps
Accelerometer
- I²C interface
- Scales of ±2 g / ±4 g / ±8 g / ±16 g
Magnetometer
- I²C interface
- Magnetic field full scale of ±4 / ±8 / ±12 / ±16 gauss
- Internal temperature sensor
Barometric Sensor BMP388
- I²C interface
- Pressure range: 300 hPa - 1250 hPa
- Resolution of data: Pressure: 0.18 Pa (eqiuv. to <10 cm)
- Absolute accuracy ±50 Pa
- Relative accuracy ± 8 Pa (equiv. to ±0.6 m)
- Temperature range -40 °C - +85 °C
- BerryGPS-IMU v3 should only be powered with a 3.3 V power supply.
