LiteRadio 3 Pro Radio Transmitter—An open-source radio remote control that supports the EdgeTX system, which is an open-source firmware for RC radio transmitters. The firmware is highly configurable and brings much more features than traditional radios. Therefore, you can try your best to customize LiteRadio 3 Pro such as language, voice and etc with the EdgeTX system.
OLED display screen with two 5D buttons is newly added to LiteRadio 3 Pro radio transmitter. Users can adjust the TX settings such as switching internal/external modules, gimbal calibration and binding on the screen by controlling 5D buttons. Compared with LiteRadio 3, it is easier to adjust such settings and very friendly to a new player.
With EdgeTX operating system, flashing ExpressLRS internal TX modules is easier for everyone. First, there is no need to disassemble the case. Compared with upgrading by WIFI, it is more convenient, fast, and stable to flash ELRS internal TX firmware by using EdgeTX passthrough flashing.
Note: Please click here to know the upgrading steps. The passthrough is only used for ELRS 2.4G version. Currently, BETAFPV is actively communicating with the ExpressLRS official team on the latest ExpressLRS configurator to support flashing LiteRadio 3 Pro ELRS TX firmware.
Nano module bay enables the external TX module available. LiteRadio 3 Pro reaches a high level with its capability to support multi-brand external TX modules in the market for different protocols such as MULTI, CRSF, PPM, XJT, DSM2, and R9M, etc. BETAFPV ELRS Nano TX Module, which features a high refresh rate, ultra-low latency, and long-range, is strongly recommended for LiteRadio 3 Pro.
Note: If you are ready to install the TBS external nano module, the TBS nano module case size should be 64*42*25mm, the thicker one of the retrofit cases.
Features four precision bearings, adjustable spring tension, and ergonomic stick ends for an unparalleled feel. With an adjustable stick end, it perfectly fits thumbs and greatly improves the stick feel for the control. Hall Effect provides contactless sensing for not only accurate control inputs and precise centering but also durable use.
