TX Module BETAFPV Micro TX V2 ExpressLRS 915MHz 2W

The BETAFPV Micro TX V2 ExpressLRS 915MHz 2W is an external transmitter module designed for radio controllers equipped with a Micro, JR or Slim module bay and CRSF output. Operating on the 915MHz frequency band with the ExpressLRS protocol, it delivers adjustable RF output from 10mW up to 2000mW, making it suitable for both close-range practice and long-range FPV flying.

Adjustable Transmission Power

Output power can be set to eight levels — 10mW, 25mW, 50mW, 100mW, 250mW, 500mW, 1000mW or 2000mW — allowing the pilot to match transmission power to the flying environment and regulatory requirements. Supported packet rates are 25Hz, 50Hz, 100Hz, 100Hz Full, 200Hz and D50.

OLED Display & 5D Button

The built-in OLED display shows current settings at a glance, while the 5D button provides intuitive menu navigation, parameter adjustment and receiver binding without requiring a separate app or computer.

Cooling System

A CNC aluminium-alloy heat sink, enlarged ventilation openings and a 2507 axial fan work together to dissipate heat during sustained high-power operation, helping maintain stable performance.

Power Input

The module accepts a main input of 7–13V DC through the controller's module bay. An XT30 port supporting 5–25V external power is also available when additional power headroom is needed. The antenna must be connected before powering on the module.

Connectivity & Firmware

A USB Type-C port is provided for firmware updates and configuration. The module ships with ExpressLRS V3.4.3 firmware (target: BETAFPV Micro 900MHz TX V2) and supports the backpack function for video transmitter control integration.
