I have 10ft long wire cabled i2c 4 buses (for 8 sensors, sensor are not in the same place each has 2 i2c addresses),
i2c accelerator will be placed in between Arduino and the i2c multiplexer input side, the output side of the multiplexer will connector 4 separate i2c buses where each end has 2 sensors
I cannot use CAN bus, also bigger circuits like i2c extenders
Is there any other way to handle this with a minimum number of components?
What are the other possible issues can occur?
I haven't selected a cable yet.
