Is there an option on the board to change I2C address selection? If so, how can I change it?

@linus777 , unfortunately changing i2c slave address of the camera is not supported by the camera drivers on VOXL2, as the i2c slave address is part of each of the `sensormodule` binaries that contain information for each camera module.

@Alex-Kushleyev 
Please, see below.

The M0061 had an I2C address selection pin.

Thanks,
Linus

@linus777 , the instructions you referenced were made for VOXL1, which had all cameras connected to the same i2c bus and slave address conflicts were not allowed. On VOXL2, each camera port has its own i2c bus and there is no possibility of a conflict when using several cameras with the same i2c slave addresses.

Is your question related to usage on VOXL1 or VOXL2?
