It should be possible to attach additional I²C slave devices to the control board’s I²C bus as long as the additional devices’ slave addresses do not conflict with that of the LSM6DS33, which uses 7-bit address 1101011. The ATmega32U4’s I²C pins (2 and 3) operate at 5 V. If you are connecting a 3.3 V device, you can connect it to the 3.3 V side of the bus instead (accessible through {{underline|Raspberry Pi GPIO pins 2}}, for SDA, and 3, for SCL, even if a Raspberry Pi is not connected). Separate level shifters might be necessary to interface with devices that use other voltages.
