Specifications
| What it is | The receiver in the aircraft, with two dual-band sections instead of one radio. It pairs to an ExpressLRS transmitter you already own |
|---|---|
| Needs a dual-band transmitter | The point of this receiver is hearing 2.4 GHz and 900 MHz together, and that takes a transmitter that sends both — a RadioMaster Nomad or another GemX dual-band module. On a plain 2.4 GHz ELRS radio it still works, but as a 2.4 GHz receiver, and the RP1 does that for less |
| Diversity | Two data streams received at once rather than one aerial picked between. A band that is being sat on by something else does not take the link with it |
| Bands | 2.4 GHz and 900 MHz, simultaneously |
| Channels | 16 |
| Output | CRSF, which every Betaflight-class flight controller reads and ArduPilot takes on a serial port |
| Telemetry power | 200 mW |
| Antennas | Four wire antennas — two for each band. They want separating and orienting apart, which is what buys the interference rejection and what makes this a big-airframe part |
| Mounting | Four 4 mm rubber dampeners in the box, so it can be isolated from frame vibration |
| In the box | DBR4 receiver, two 2.4 GHz antennas, two 900 MHz antennas, CRSF lead, four dampeners |
| Weight | RadioMaster publish no board weight for this one. The listing's 18.14 g is the packed kit — for comparison, the same listing style gives the RP1 as 9 g where RadioMaster's own figure is 2.2 g. Expect it to be several times an RP1 either way: it is a bigger board carrying four antennas |
| Manufacturer | RadioMaster |
