Jumper T20 V2 ELRS 868/915MHz

Jumper T20 V2 is a high quality radio with EdgeTX firmware and 1W ELRS module. The Jumper T20 is the ideal choice for those looking for a small radio without compromise. The radio is 185x188x68mm in size, which is noticeably smaller than the Boxer or TX16. Even at this size, however, it uses large hall gimbals. As with the larger radios, the Jumper T20 V2 will provide 6 switches, 6 potentiometers. There are six adjustable buttons. There are also joysticks on the radio for trim settings, but these can be reconfigured and used as additional switches. For ease of transport, it has a folding swivel antenna. All information is displayed on a 1.3" OLED display. A great advantage is the integrated memory that replaces the classic SD card, which greatly increases the reliability of the radio.

On the back we find an active cooling for the ELRS module. The power supply is also worth mentioning. The shaft can accommodate two Liion batteries (not included). The radio has a shaft for the larger 21700, which will noticeably extend the battery life. The batteries are conveniently charged via the USB-C connector.

The big advantage of the radio is the aforementioned integrated ELRS module at a frequency of 868/915MHz with power up to 1000mW. ExpressLRS (ELRS for short) is an open source project and the transmitting and receiving modules are produced by multiple manufacturers. ELRS is currently one of the most advanced RC transmissions. It offers reliable long distance link, high refresh rate, adjustable power, update via wifi and more. ELRS at 868/915MHz is especially suitable for long distance flights

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