Reply To: UM7 Expansion Board

[John Mower]

DO you mean the USB expansion board? No, you don’t need it as the UM7 has a 3.3 volt logic serial interface. If your interface can do 3.3 volt serial, you’re in good shape. That said, If you want to use the CHRobotics software for monitoring/testing/calibration you will need some sort of device that registers itself as a virtual com port to interface with their software (the USB expansion board with the 5 wire cable does this)
