I’m relatively new to working with the Cube, and I have a question regarding voltage measurements.
I’m currently designing the electronics for a drone, with two completely isolated battery systems. Two 6S batteries connected in series will power the ESCs and motors. One 4S battery will power a Cube Orange and all remaining electronics. The only “connection” between these systems are the control signals for the ESCs, which are galvanically isolated.
I’m planning on using a Holybro PM02 connected to the POWER1 port to power the Cube from the 4S battery and get voltage and current measurements. Is it possible to use the POWER2 port to get voltage measurements from the 6S batteries without having a common ground?
