SPIDER Automation | BETAFPV LiteRadio 2 SE FPV Radio Transmitter – 2.4GHz, 100mW & 1000mAh Battery | Configurator and USB Simulator Support
Product Overview & Radio Control Design
The BETAFPV LiteRadio 2 SE Radio Transmitter is an upgraded version of the LiteRadio 2, developed to provide improved transmitting power, extended battery endurance and convenient radio configuration functions. Its ergonomic gaming-controller-style construction is designed for comfortable operation, with a rubber-coated exterior and anti-slip texture on the handles.
The transmitter supports a specified frequency range of 2403–2447MHz and a maximum transmitting power of 100mW. The LiteRadio 2 SE product family is available in different protocol configurations, including an ExpressLRS 2.4GHz version and versions supporting protocols such as Bayang, Futaba S-FHSS and FrSky D8/D16. Protocol availability depends on the exact hardware variant.
The ELRS 2.4GHz version supports BETAFPV Configurator, a utility designed to simplify transmitter firmware updates, configuration and tuning. The customised BETAFPV LiteRadio System also provides joystick calibration and firmware update functions directly through the transmitter.
A built-in 1000mAh 1S battery provides up to 8 hours of stated operating time. Integrated charging circuitry supports USB charging through the USB Type-C connection. When connected to a compatible computer, the transmitter can also function as a USB joystick for supported FPV flight simulators.
