SPIDER Automation | BETAFPV LiteRadio 2 SE ELRS 2.4GHz Radio Transmitter – SX1280, 8 Channels & 100mW | Rechargeable Battery & Simulator Connectivity

Product Overview & Radio Control Technology

The BETAFPV LiteRadio 2 SE Radio Transmitter is an upgraded version of the LiteRadio 2, designed for FPV radio control applications with improved transmitting power, integrated battery capacity and convenient configuration features. This version supports the ExpressLRS 2.4GHz radio link protocol and uses the SX1280 2.4GHz system.

The transmitter features a built-in 1000mAh 1S rechargeable battery that provides up to 8 hours of operating endurance. Its transmitting power reaches up to 100mW, while the 8-channel configuration supports compatible radio control systems.

LiteRadio 2 SE incorporates BETAFPV’s customized LiteRadio System, allowing users to perform joystick calibration and firmware updates directly through the transmitter. It also supports the BETAFPV Configurator utility for updating, configuring and tuning the radio controller.

The controller can function as a USB joystick when connected to a personal computer, enabling use with supported FPV simulator applications. Its rubber-coated ergonomic housing and anti-slip handle texture are designed to provide a comfortable grip during extended operation.
