3.4. Tachometer Input
The Propeller Control Board includes a tachometer input that can be connected to the magneto of an
engine to determine its rotation speed. To be functional, the tachometer input requires the Propeller
Control Board's electrical ground to be connected to the QUADROVER chassis ground. See the
precautions in section 3.3 before connecting the tachometer.
