Connecting 3 IMUs to Mrduino Mega

Hi, I am working on a project for which I need to connect three digital IMUs to an arduino mega 2560. Can someone suggest the circuit connections for this. Thanks in advance. Good day to all.

That would depend on the type of IMU, don’t you think?

It is a 9dof imu https://learn.adafruit.com/adafruit-bno055-absolute-orientation-sensor/wiring-and-test

Seems to have only 2 I2C address settings though. There is also an HID_I2C address, not sure if that's equivalent.

For some reason IMUs have standardized on I2C not SPI, and its a pain (as you are discovering).
