Hi there I am currently attempting the wire one of atles scientific tentacle shields along with two tca9548A multiplexers an a single Arduino mega, can you please tell me wether this is feasible or can the mega only by connected to the tentacle alone.

King regards Michael.k

Yes it can be done... read their instructions but the back of the board has I2C addresses that can be set by soldering

Notice the A0, A1, A2 jumper pads. You can change the address by bridging with solder or 0 Ohm resistors. Check datasheet for more info.
