The Jumper Bumblebee is a small gamepad-shaped transmitter suitable for beginner and advanced pilots. The Jumper Bumblebee is the successor of the Jumper T-Pro. With its dimensions 160x128x68mm, it is one of the smallest gamepad radios. The rotatable and foldable antenna facilitates transport and allows adjustment to the optimal position during operation. The transmitter uses EdgeTX firmware and an integrated ELRS module with full power up to 1W. Power is supplied by dual 18650 Li-ion batteries (not included), which are charged via a USB-C connector. All information is displayed on the 1.3" OLED display. Jumper Bumblebee uses high-quality hall gimbals with bearings. There are two switches, four buttons, two potentiometers, and six-position buttons. When using the Jumper Adapter, an external transmitter module can be added to the radio in the Nano Shaft. The radio has a built-in speaker for both voice alarms and haptic response. An advantage is the integrated memory, which replaces the classic SD card, greatly increasing the reliability of the radio. Also included is a practical case. The radio has a replaceable front yellow panel, which can easily be replaced with a panel of a different color.
The big advantage of the radio is the aforementioned integrated ELRS module with a power output of up to 1000mW and a refresh rate of up to 1kHz. ExpressLRS (ELRS for short) is an open-source project and both transmit and receive modules are produced by multiple manufacturers. ELRS is currently one of the most advanced RC transmissions. It offers reliable long-distance link, a high refresh rate, adjustable power, updates via wif,i and more. ELRS at 2.4GHz outperforms conventional RC systems in every way while maintaining short antennas.
