User Manual
Input: Power Module
Documented as "VI Sense"
If you are using the power module (from HK or 3DR) its supplied cable will plug into the 'VI
Sense' port correctly.
The Red and Black wires go to Vcc, and Gnd as expected. Again the pin-out is clearly printed on
the bottom of the board in a square box if you need it.
