FrSky D4FR 4CH 2.4Ghz Receiver
Compatible with FrSky two way telemetry modules: DFT, DJT, DHT, DHT-U
Operating Voltage Range: 3.5V-10.0V
Operating Current: 60mA
Operating Range: Full Range
Resolution: 3072 (>11bit)
1) Lighter weight and physically smaller than D8R-II & D6FR;
2) RSSI (PWM) and CPPM output - If CH3 and CH4 are connected by a jumper, CH1 will output RSSI (PWM), and CH2 will output CPPM for CH1~CH8;
3) Simple wire antenna and another U. Fl antenna connector;
4) Alarm warning on low voltage, poor reception, etc.
trs bonne porte font le boulot dommage que les V2 ne soit pas dispoextremely compact but compared to 6 chanel one it dont have really added value. reception and quality is ok, but next time I will buy only the 6 channelGreat RX, its very small and lightweight. I'm using this for my quadcopter.just fried one, be careful do not reverse polarity, there`s no diode for protection at all, also cppm function is to sensetive ,with almoust any servo or cheap becs like in HK blue series20A ESC`s all channels going crazy making impossible to use this function( i used it with multiwii copter, so quadcopter was fine, but tricopter with servo became useless) so if you think to use it as cppm reciever with servo in setup, think twice.Hello:
The receiver comes with two jumpers. How i have to connect them to obtain CPPM in CH2 ?
Signal of CH2 to and Signal CH3 yo too.
Or signal CH2 with signal CH4 ? ... it is not clear in the instructions.
Carefully rangetest these little ones. In spite of having two antennas, it has no diversity. Top choise for parkfliers and small copters, not recommended for large gliders. Gives ppm-sum signal if wanted (8 channels). Can store failsave for every individual channel.using this jumpered for ppm sum. Wish the price would drop some but I cant imagine that these don't sell still.Nice Receiver - so small so chip - good choiceThis thing is small and realy lightweight but that doesnt mean it is not good as a bigger brothers.It have build voltage sensor(bec or ubec users beware cause u/bec will supply steady voltage all the time).It is suitable for most smallest planes, you can remove case and put it in heatshrink and bam less than 4g grams.how is this 4 channel receiver to use?
i want to use it in a small jet throttle and aileron.
and i want to use the gps with the sensor hub for speedmeasurement.
is that possible
i do not understand these veryvery short "discriptions"
