SPIDER Automation | BETAFPV LiteRadio 3 Pro 8-Channel Radio Transmitter – EdgeTX, Hall Gimbals & 2000mAh | Multi-Protocol RF Control & OLED Interface
Product Overview & Radio Control System Design
The BETAFPV LiteRadio 3 Pro Radio Transmitter is an open-source radio control transmitter designed around the EdgeTX operating system. Its configurable firmware platform allows users to customize transmitter settings and control configurations according to their supported radio-control applications.
The transmitter features precision Hall-effect gimbals with four precision bearings, adjustable spring tension and ergonomic stick ends. These mechanical features provide adjustable stick feel and controlled input for radio operation.
A 1.3-inch OLED display is positioned on the top of the transmitter. Two 5D buttons provide access to the display interface, allowing users to view information and adjust transmitter settings directly. The transmitter also integrates a 2000mAh 1S battery, providing up to 15 hours of operation without an external RF module, as specified by the manufacturer.
LiteRadio 3 Pro supports different RF configurations, including ExpressLRS 2.4GHz and CC2500. A reserved nano module bay also allows the use of compatible external TX modules, providing additional protocol options. USB Type-C and 3.5mm audio connectivity support simulator use, charging, firmware updates and audio connection requirements.
