BetaFPV LiteRadio 3 Pro Radio Transmitter — Full Description

The LiteRadio 3 Pro Radio Transmitter from BetaFPV is a compact and versatile drone remote control that combines open-source EdgeTX firmware, increased power of the internal ELRS module, and extended compatibility with external nano TX modules. The transmitter features high-precision Hall effect gimbals, ergonomic stick ends, and a 1.3-inch OLED display for quick access to settings during flight.

Key Advantages and Features

LiteRadio 3 Pro offers an internal ELRS module with adjustable output power up to 250mW (50mW, 100mW, 250mW modes) for significantly increased range and connection stability. It also supports the CC2500 protocol with 100mW mode. A bay for an external nano TX module is provided, allowing the use of popular modules and protocols on the market: MULTI, CRSF, PPM, XJT, DSM2, R9M, and others. The device officially supports EdgeTX firmware, which unlocks extensive customization options for the interface, language settings, and voice prompts.

Design Features

• Hall Gimbals with contactless sensing ensure high precision, durability, and reliable centering; the design includes four precise bearings and adjustable spring tension.
• 1.3-inch OLED Display at the top of the transmitter with two 5D buttons provides intuitive menu navigation, quick mode changes, and calibration without additional equipment.
• Built-in 2000mAh 1S Battery allows up to 15 hours of operation without an external module, and the USB Type-C (USB 3.0) port is used for charging, firmware updates, and connecting to simulators.
• Protocol Support: ExpressLRS 2.4G and CC2500 (Corona, Hitec, Futaba S-FHSS, Frsky D/X, RadioLink, Graupner HoTT, etc.), making the transmitter compatible with a wide range of receivers and modules.

Firmware Update and EdgeTX Operation

Official EdgeTX support allows for easy interface updates, function customization, and internal ELRS module updates without disassembling the casing. The update process is simple and stable: connect via USB and upload the firmware through a user-friendly interface.

OLED Display and Control

The OLED screen and two 5-D buttons allow for quick switching between internal/external modules, gimbal calibration, and pairing. The left and right 5-D buttons are used for navigation, selection, and confirmation of on-screen parameters; the black switches can lock the gimbal hold function.

External TX Module Slot and Compatibility

The nano bay for an external TX module allows connecting modules from various brands and working with MULTI, CRSF, PPM, XJT, DSM2, R9M, and other protocols. For maximum refresh rate and minimal latency, the BETAFPV ELRS Nano TX module is recommended, although other manufacturers are also compatible.

Gimbals and Ergonomics

Hall effect gimbals provide contactless sensing and precise centering. Four bearings in the design, adjustable spring tension, and ergonomic grips enhance control comfort even during long flights and competitions.

Controls and Boot Mode

Power button: hold to turn on/off. To enter boot mode, turn off the transmitter, simultaneously press the boot button and the power button, then release. This allows for quick firmware updates and service operations.
