The Jumper RX is a compact, lightweight radio control receiver that uses the ExpressLRS protocol for long-range performance and low latency. It is compatible with ELRS 2.4 GHz transmitters, so it works with the many radios and modules that use ExpressLRS.
It supports 16 channels and offers full-range operation exceeding five kilometres. The board measures 17.2 x 8.8 x 4.3 mm, weighs 1.1 g and draws about 60 mA at 5 V.
Operating voltage is 3.5 to 6 V, so it can be powered from a flight controller's 5 V pad, and its low current draw means it hardly loads the supply. Integrated failsafe means the receiver reacts predictably if the link drops, but you should still configure your flight controller's failsafe behaviour and test it on the bench before flying.
As with any tiny receiver, mount it away from carbon fibre and motor wires, keep the antenna out in clear air, and support the solder joints with heat shrink. Bind it to your ExpressLRS transmitter module using the shared binding phrase.
Pilots who want an inexpensive, light ExpressLRS receiver for quads and small aircraft, and who value the long range that the protocol provides.
Most small ExpressLRS receivers are built from similar chips, so the differences come down to size, antenna style, power draw and price. The Jumper RX sits at the light and low-current end of the range, which is why it suits builds where every gram and every milliamp counts. Before ordering, check that your flight controller has a free UART for CRSF and a 5 V pad, and that your radio uses ExpressLRS 2.4 GHz.
