Jumper Smart ELRS 2.4GHz Radio Controller

The Jumper Smart is a compact, budget-friendly handheld radio transmitter with a built-in ExpressLRS 2.4GHz module, for pilots flying ELRS-equipped drones or wanting a lightweight backup radio.

Key features

• Built-in ELRS module gives low-latency, long-range 2.4GHz control without needing a separate external radio module.

• Hall-sensor gimbals on 8 ball bearings give smooth, precise stick feel.

• 2-inch colour IPS screen (320x240) stays legible in bright outdoor light for menus and telemetry.

• Foldable antenna and a compact, lightweight, ergonomic body make it easy to carry alongside a full-size radio.

• Runs on a single rechargeable 18650 battery cell, charged conveniently over USB-C.

• 3.5mm simulator port lets it double as a controller for flight-sim practice, and it runs JumperTX firmware alongside its ELRS module.
