I just added an AttoPilot to my setup, mainly to monitor current consumption. Has anyone else done this?
In MP, all I see is 0 current consumption, no matter how much load I put on the circuit. When I use a DMM to measure the signal coming from the AttoPilot board, (across GND and I) I see the voltage go from 0.0013v under no load to -0.0015v with motors spinning (no props on) and LEDs on. I find it odd that these signal voltages are so low, the differences so small and even odder that they go negative. Has anyone else seen this? Am I doing something wrong?
With a 4S LIPO attached (14.93v) the voltage signal pin is 0.96v.
I bought the 90 amp version, I'm wondering if I should have gotten one with a smaller capacity. I'm running 3 motors which I'm expecting to draw about 15 amps each tops, a few LEDs and the electronics.
