SPIDER Automation | BETAFPV LiteRadio 3 8-Channel Radio Transmitter – 2.4GHz, 100mW & 2000mAh Battery | Nano Module Expansion & Simulator Connectivity
Product Overview & Radio Control Technology
The BETAFPV LiteRadio 3 Radio Transmitter is an 8-channel radio controller designed primarily for RC models, including multirotor and airplane applications. As part of the LiteRadio series, it combines an ergonomic controller-style housing, an updated joystick gimbal and multiple protocol options in a compact radio control platform.
LiteRadio 3 is available in ExpressLRS 2.4GHz and FrSky protocol versions. The ELRS 2.4G version uses ELRS V3 as its default firmware for units supplied since November 2023, replacing the earlier ELRS V2.0 firmware. The FrSky version supports the protocol modes identified in the supplied product information.
The transmitter incorporates a built-in 2000mAh 1S rechargeable battery, providing up to 15 hours of operating time without an external TX module. A built-in charging module supports USB charging, while the Nano module bay allows connection of a compatible external transmitter module. With a compatible external module, CRSF protocol availability is also supported as described in the supplied information.
For configuration and simulator use, LiteRadio 3 supports BETAFPV’s customized LiteRadio System and BETAFPV Configurator. Users can perform joystick calibration and firmware updates, while USB joystick functionality enables connection to compatible practice simulator software through a computer.
