iBUS RC voltage sensor

This project is a device that is FlySky-compatible i.BUS voltage sensor. It is implemented with an AVR ATmega328P, and for use with 3S or 4S LiPo batteries on board an RC plane.

The code and schematics are available here https://github.com/eyalabraham/ibus-volt-sense on GitHub, and were based on on an implementation for a single wire FlySky I.Bus telemetry device https://github.com/betaflight/betaflight/wiki/Single-wire-FlySky-(IBus)-telemetry
