Jumper T22 CNC Hall ELRS 868MHz/2.4GHz

Jumper T22 CNC Hall is a full-featured RC transmitter suitable for advanced FPV drone and RC airplane pilots. Its main advantages are a dual-band ELRS module for 2.4GHz and 868MHz, all-metal CNC Hall gimbals, and a tilting 3.5" IPS colour display. The manufacturer also refers to it as the T22 Duo. This version comes in blue.

The gimbals are all-metal, CNC-machined from aluminium, with contactless Hall sensor detection — control is precise and the sensors do not wear out. Stick height can be adjusted, and stiffer springs for adjusting tension are also included. Additional model controls include two 2-position and two 3-position switches, a 6-position switch, 2 rotary knobs, 2 sliders (analogue throttle slider), and a rotary scroll wheel on the shoulder. The transmitter also has 6 separate RGB backlit buttons, suitable for example for switching airplane flight modes or controlling payload release; labels for them are included. Settings are controlled by machined backlit menu buttons and a rotary encoder.

The 3.5" display with 480x320 resolution is IPS type and sits in a CNC-machined frame that can be easily removed for display replacement or servicing. The radio is powered by an STM32H750 processor. Instead of a removable SD card, it has integrated memory, increasing the radio's reliability. The transmitter uses fully configurable EdgeTX firmware (the successor to OpenTX). A reinforced speaker chamber provides louder and clearer voice announcements, and the transmitter has programmable RGB LED backlighting (WS2812).

A major advantage of the radio is the integrated ELRS module with output power of up to 1000mW, operating on two bands — 2.4GHz for racing and freestyle with minimal latency and 915MHz for long-range. ExpressLRS (ELRS for short) is an open-source project, and transmitting and receiving modules are manufactured by multiple brands. ELRS is currently one of the most advanced RC links — it offers a reliable long-range link, high refresh rate, adjustable power, and updates via Wi-Fi. The module is actively cooled by a fan. The dual-band antenna is foldable and rotatable, and the transmitter has prepared openings for possible antenna replacement.

On the rear, there is space for installing a Nano bay for optional expansion with an external transmitter module and a trainer port. The transmitter is powered by two 21700 cells (input voltage 6-8.4V), charged via a USB-C connector at up to 10W. USB-C is also used for connecting to a simulator (joystick mode) and file management on a computer. The package includes a case, neck strap, and display protective film.

Batteries are not included.
