Jumper T20 V2 ELRS - ausgepackt

Jumper T20 V2 is a quality radio with EdgeTX firmware and a 1W ELRS module. The Jumper T20 is an ideal choice for those looking for a compact radio without compromises. The radio measures 185x188x68mm, which is significantly less than the Boxer or TX16. Despite this size, it uses large hall gimbals. Like larger radios, the Jumper T20 V2 offers 6 switches and 6 potentiometers. Additionally, there are six adjustable buttons. The radio also features joysticks for trim adjustment, which can be remapped and used as additional switches. For easier transport, it has a foldable rotating antenna. All information is displayed on a 1.3" OLED screen. A significant advantage is the integrated memory that replaces the traditional SD card, greatly increasing the radio's reliability.

On the back, we find active cooling for the ELRS module. Also noteworthy is the power supply. The compartment can fit two Li-ion batteries (not included). The radio has a compartment for a larger 21700, which significantly extends the battery life. Batteries are comfortably charged via a USB-C connector.

A major advantage of the radio is the mentioned integrated ELRS module with a power of up to 1000mW and a refresh rate of up to 1kHz. ExpressLRS (abbreviated ELRS) is an open-source project and both transmitting and receiving modules are manufactured by multiple manufacturers. ELRS is currently one of the most advanced RC transmissions. It offers a reliable link over long distances, high refresh rates, adjustable power, updates via Wi-Fi, and more. ELRS at 2.4GHz outperforms traditional RC systems in every aspect while maintaining short antennas.  

The Jumper T20 and T20S transmitters differ in the gimbals used. The Jumper T20 uses hall gimbals, while the Jumper T20S uses premium RDC90 gimbals. Version 2 primarily uses active cooling and a more powerful processor.
