Jumper Bumblebee ELRS 1W 2.4GHz Radio Controller

The Jumper Bumblebee is a compact FPV radio with a built-in 1 W ELRS 2.4 GHz transmitter, Hall-sensor gimbals and EdgeTX firmware. It suits pilots who want long-range ELRS control in a small case, and the external Nano bay leaves room to add a Crossfire or Tracer module later.

Key features

• Internal ELRS RF module with up to 1000 mW (30 dBm) output

• Hall-effect gimbals for contactless, wear-free stick sensing

• 1.3-inch OLED screen for menus, model setup and telemetry

• External Nano module bay accepting ELRS, Crossfire and Tracer Nano modules

• STM32F407VGT6 processor, independent boot button for firmware flashing, and USB-C charging

• Foldable, adjustable antenna

Budget for two good-quality 18650 cells, as none ship with the radio. Your receivers need ELRS 2.4 GHz firmware on the same major release as the radio's internal module to bind, so update both before the first flight.
