I'm building a quadcopter using and APM 2.6 finances means I can't change to a different board. I have a simple question (I think) How do I connect the 4 wires from RWC-0001 sensor to the APM 2.6 board which wire goes to which pin According to the pages and pages I've read the sensor connects pin group A0 but. there are only three pins.
If someone could just say VCC fits to this pin, Gnd fits to this pin, echo fits here, trg fits here.
You're help would be appreciated
