Radiolink R12DSE 12-Channel Receiver with Dual Antennas

A small receiver with real reach

The Radiolink R12DSE is a 12-channel receiver with dual antennas that offers up to 4,000 m of control range using DSSS and FHSS spread spectrum. It provides SBUS and PPM outputs with a 3 ms latency and weighs only 2.5 g, measuring about 1.2 x 0.47 inches.

Precision is high: the receiver gives 4096 resolution with 0.25 microsecond servo output. Reverse polarity protection is built in, and the input range is 3 to 6 V DC.

Telemetry and compatibility

Telemetry is available through the optional PRM-03 module. The receiver is RoHS, CE and FCC certified. It is designed to work with Radiolink transmitters that use the same protocol, so check that yours does before you buy.

For installation, keep the two antennas at different angles and away from carbon fibre and power wires, bind it to your transmitter, set failsafe and test each channel. The product name and the specification list SBUS and PPM in one place and PWM and SBUS in another, so confirm the output you need with the manual.

Who should use it

Pilots of drones, planes and cars who want a light 12-channel receiver with a long range and SBUS output for a flight controller.

SBUS or PPM?

SBUS carries all twelve channels on one wire and is the usual choice for modern flight controllers, while PPM is an older single-wire format that some controllers still expect. The receiver can output both at once, so you can pick whichever your controller supports. Check your flight controller's receiver setting and make sure the signal is inverted or not, according to its manual.
