Mini VBar RPM sensor

Using a mini VBar with the governor you should know there is a limitation of the ingoing voltage at RXA (brown, upper pin) with 5V maximum. The Vbar could be damaged if using a higher voltage there.

But ... the input works from approx. 2.5 V up to 5V safely. So we can present a common solution for all RC voltages over 5V up to 2s LiPo here. We use a simple voltage divider with 2 resisitors of 1000 Ohm (1 kOhm). The cheap 1/4 W types are good enogh here.
