After watching Episode 19, I have a question about using satellite port to provide power to RPM sensor. MrMel did mention that if HV system was used, we could use satellite port to provide power to the RPM sensor (an alternative).

Last night, I measure the voltage of satellite port (pin 1 and 2, counting from the servo port side). Voltage was about 3.25V when I used a 6.6V LiFe battery connected to RXB port.

The 3.25V was not enough to drive the RPM sensor. Do I need to use 2S LiPo battery 7.4V to Mini Vbar in order to get a higher voltage out of the satellite port ?
