Feature

1) Firmware upgradeable;
2) One external analog telemetry port and one digital data-stream port (connect to FrSky Sensor Hub FSH-01);
3) RSSI (PWM) and CPPM output - If CH3 and CH4 are connected by a jumper, CH1 will output CPPM for CH1~CH8, and CH2 will output RSSI (PWM);
4) Lighter weight and physically smaller than D8R-II plus & D6FR;
5) 2.4G FrSky Two Way Receiver

Description

D4R-II is a full featured mini sized 4 channel receiver, The D4R-II's data port allows you to connect a sensor hub so you can connect GPS, Variometer, temperature, RPM and all of the other great FrSky sensors. if the jumper is used on CH3&CH4 it does output a 8 channel PPM stream plus a RSSI voltage signal on channel 2. Perfect for FPV.
