Big Quad: volt/cur mon

Post by theseankelly »

I've started wiring up my big quad and I'm not 100% sure what to connect to the monitor port. I imagine gnd and vbat should tie in directly to my battery's leads, right? What gets connected to the current monitoring pin?

As the firmware still isn't so developed for these functions they don't do so much yet... :oops:

As you figured out the voltage connects directly to the battery voltage. For the current monitor you need a monitoring circuit with an voltage output between 0-3V. E.g. something similar to this. It needs to be configured with the correct multiplier as well.

That's fine -- I intend to make them do something (probably just send telemetry back to my Devo)
