Connecting BerryIMU to a Raspberry Pi
BerryIMUv2 only supports I2C and connects as shown below.
BerryIMUv3 supports I2C and SPI.
The BerryIMUv3 also works with the Raspberry Pi Pico
By default, the BerryIMUv3 is configured to work with I2C. To use SPI, you will need to close jumper JP7 (shown below) to complete the SPI connection. This can be done by placing a solder blob on the jumper.

BerryIMU i2c Addresses
BerryIMUv2
The default i2c addresses on the BerryIMUv2 are;
- 0x6A for the gyroscope and accelerometer
- 0x1C for the magnetometer
- 0x77 for the pressure sensor
Solder the pads on JP2 together will change the address for the accelerometer and magnetometer from 0x1C to 0x1E.
Solder the pads on JP5 together will change the address for the gyroscope from 0x6A to 0x6B.
BerryIMUv3
The default i2c addresses on the BerryIMUv3 are;
- 0x6A for the gyroscope and accelerometer
- 0x1C for the magnetometer
- 0x77 for the pressure sensor
Solder the pads on JP12 together will change the address for the magnetometer from 0x1C to 0x1E.
Solder the pads on JP5 together will change the address for the accelerometer and gyroscope from 0x6A to 0x6B.
