does the GND output pin share the signal from battery GND (the large PCB trace with the “-”) ?
if I use an isolated DC/DC converter to power my autopilot board may I have GND reference problems with this sensor (e.g. ground loops) ? My wiring scheme would be: battery -> ACS759 sensor -> isolated DC/DC -> autopilot board
My doubt now is that, if I don’t connect the GND of the connector on your board I may have a floating voltage reference since my flight board is powered by the isolated DC/DC which supply its own GND reference which could be different from the battery GND, giving a misleading voltage reading.
I’m facing this problem since some days ago, so if you have any more suggestion to help me go through this problem it would be great,
