I have bought an Otii and now would like to use to measure power consumption of BG96 modem. I need to connect an external voltage to Otii and in the same time need the Otii to be connected with my laptop to collect data. On the other hand I need to connect my laptop to the modem over USB to send commands. So multiple voltage sources will be connected to the modem, i. 3.3V through the USB ii. another 5 v though the Otii (Otii is connected to both laptop and external source). Should it work, I am mostly scared if I fry the modem.
