WARNING!
SmartAP 3.x gets power directly from the PDB connected to the main battery, therefore, supply voltage is the same as your battery voltage
and it can be up to:
36V (8S) for SmartAP 3.0
36V (8S) for SmartAP 3.1
Wiring between the Power Distribution Board and the Autopilot should look as following:
SmartAP MAX
SmartAP MAX gets the power supply and voltage / current readings from the PDB using standard 6-pin cable with Molex PicoBlade connectors.
Simply connect the cable to PWR connector of the autopilot.
