This version includes an integrated voltage regulator and a jumper pin that allows the selection between 5v source or a 2s+ lipo battery balance connector to power the device. It also has a built in push button for changing transmitter IDs on the fly and saving them in eeprom memory. serial tx and rx are also broken out so the ID can be programmed via serial.
