SPIDER Automation | BETAFPV LiteRadio 3 Pro Radio Transmitter – 8CH, ExpressLRS 2.4GHz & EdgeTX | Precision Hall Gimbals, 250mW RF Output & OLED Interface
Product Overview & Radio Control Technology
The BETAFPV LiteRadio 3 Pro Radio Transmitter is an open-source radio control transmitter designed around the EdgeTX operating system. It combines configurable transmitter software, precision Hall-effect gimbals, an OLED display and multiple RF options in a single control unit.
The transmitter features Hall gimbals equipped with four precision bearings, adjustable spring tension and ergonomic stick ends. This mechanical arrangement is designed to provide smooth stick movement and precise control input. The integrated 1.3-inch OLED display provides a visual interface for operating information and transmitter settings, with adjustments made through two 5D buttons.
The LiteRadio 3 Pro offers two internal RF system options: ExpressLRS 2.4GHz and CC2500. The ExpressLRS version supports selectable RF output power up to 250mW, while the CC2500 version supports a range of specified radio protocols. An additional nano external TX module bay allows the transmitter to work with compatible external RF modules for expanded protocol support.
Power is supplied by a built-in 2000mAh 1S battery, which provides up to 15 hours of operation without an external TX module. The transmitter also includes a USB Type-C port and a 3.5mm audio port.
