Description

BerryIMU v3 is an inertial measurement unit, or IMU, that measures and reports on velocity, orientation and gravitational forces, using a combination of an accelerometer, gyroscope and a magnetometer.

BerryIMU v3 is also fitted with a barometric sensor (BMP388) which can be used to calculate altitude. A temperature sensor is also included.

Features:

• Gyroscope and accelerometer output rates of 6.7KHz (6,664 times a second!)
• Detect tilt, tap and double tap
• Pedometer, step detector and step counter
• Interrupt pins
• Read temperature
• supports both 3.3V and 5V
• I2C and SPI
• “Always-on” experience with low power
  consumption for both accelerometer and gyroscope

IMUs can be found in devices like, quad copters, smart phones, segways, Wii Remote etc.. and are used to sense movement and orientation.

Adding BerryIMU  to your  Raspberry Pi, Adruino, teensy  or ESP8266 will open up a whole new world of possibilities.

BerryIMUv3 is designed to take some of the complexity out of IMUs and to try and make them more enjoyable  to use. BerryIMUv3 includes the latest and greatest sensor ICs.

3.3V and 5V compatible (We have included logic level shifters for 5V use)

BerryIMUv3 is compatible will all models of Raspberry Pi (including Pico), It is also compatible with Arduino, Teensy and the  ESP2866.

We have also made the BerryIMUv3 compatible with the SparkFun QWIIC echo system.

We sell a QWIIC connector and cable for the Raspberry here.  This does away with the need to solder headers onto the BerryIMUv3 when connecting to a Raspberry Pi.
