NR502T-F2 Receiver Specification:

NR502T series of receivers are super small size but long range and supporting data back receivers designed specially for FPV flight. High efficiency PA and LNA are integrated onto its hardware, also two bidirectional serial ports are integrated. Several kinds of communication protocols are switchable conveniently.; We can provide up 2 types of this series receivers, all of them can be used on any F4 and F7 flight control board with or without signal inverter. 

Features: 

1） Super small size

2） Super light 1.6g 

3） All NR502T series receivers can be used on any F4 and F7 flight control board with or without signal inverter. 

4） Can connect and work on any serial port of F4 and F7 flight control board; 

5） IPEX4 antenna plug; 

6） Diversity antenna provides best range and best radio frequency performance! 

7） Supports data-back function (Note: B1 version doesn’t support this function as it is limited by its protocol) 

8） Supports working temperature measurement; 

9） Supports RSSI output; 

10） Supports reversed SBUS 

11） Supports normal or reversed FPort 

Compatible transmitter : FRSKY Jumper T16 

Binding operation: Press the binding switch after NR502T receiver is powered, it enters binding mode after 2 seconds when the slow flashing red LED turns to fast blinking. Then bind the receiver according to the transmitter manual. When the fast blinking red LED turns to solid bright, it indicates binding is successful. Variable RF Link technology: Variable RF Link technology: When the receiver is too close to radio(remote control), normally RF signal will be blocked and meanwhile lose control happens, Variable RF Link is born for solving the problem! As soon as Variable RF Link finds that the receiver is coming close to radio, it will adjust LNA gain and PA output power lower to avoid short distance control failure automatically; When Variable RF Link detects that the receiver is going far away from radio, it will adjust LNA gain and PA output power higher to increase RX’s working range automatically.
