Recievers (RX700)

RX700NR

The receiver board: 26 x 54mm.

Weight: 6.5 gr. (8.5 grams including wire)

Sensitivity: -102dBm.

Input supply voltage range: 4-10V.

Servo signal pulse output: 3.3V positive.

Radio band: 433 & 444 MHz multi band and multi frequency hopping system.

Temperature range: -40C to +70C tested.

Receiver 8ch - optimized input filter so it can co-exist with strong 2.4 GHz on board video transmitters.

Wire antenna mounted directly on the Rx.

The extra pin in ch 12 connector is RSSI out. Ch 12 connector is also PPM out when < 12ch are used.

PPM out is the same as sum-signal and this is of course fully compatible with MikroKopter controller board, all RX have this SUM and RSSI out.

RX700LR

This receiver have improved input filter and makes it now even better attenuation for 900 - 1300 - 2400 video transmitters. This is virtually impossible to jam. The Rx700LR also have improved distance of the servo connector and now all 12 can be mounted at the same time and no bending or problems.

The receiver have the following dimensions:

Width: 34 mm.

Length: 62 mm. including angled connector.

Height: 10 mm.

Weight: 16 gr.

The receiver uses a Double LNA (Low Noise Amplifier) frontend with fast signal switch so it uses the best signal.

Two MCX connector coax dipole wire antennas come with each RX t – Weight: 5.4 grams each.

The extra pin in ch 12 connector is RSSI out. It’s now buffered so loading of the RSSI out is uncritical, 1k ohm Zout. It is also filtered to avoid less jumpy OSD readings.

CH 12 connector is also PPM out when < 12ch are used (auto mode is the default).

PPM out is the same as sum-signal and this is off course fully compatible with MikroKopter controller board and all RX types and models have this.

Sensitivity: -113dBm to -114dBm
Input supply voltage range:  4-6V (Rx uses 134mA at 5V)
Servo signal pulse output: 3.3V positive
Radio band: 433 & 444Mhz multi band and multi frequency hopping system.
Temperature range: -40C to +70C tested

LED indicators

The NR got one LED it simply indicates valid supply voltage.

The LR got two LED’s one located near each antenna connector.

The normal operation of the LED’s are during flight and installation to show what antenna signal is the strongest, since that is the selected signal.

FAST Blinking LED during power up indicate search mode.

FAST Blinking LED during flight indicates failsafe is recalled and search mode is now running.
