The HPXGRC ELRS 2.4G 1W Micro TX Module is a high-power Micro-standard transmitter designed for installation into radio controllers with a compatible module bay. Operating on the open-source ExpressLRS protocol, the device ensures maximum packet rate updates and minimal signal latency, which is critical for controlling high-speed aircraft at extended ranges. With an output power of up to 1W and an efficient active cooling system, the module guarantees stable communication even in environments with dense radio interference and challenging terrain.

The hardware is built on reliable components that ensure precise frequency generation and output signal stability without power drops during prolonged operation. The HPXGRC ELRS 2.4G 1W Micro TX Module features a clear built-in display and a user-friendly interface for rapid setting adjustments directly in the field, while the inclusion of an XT30 connector for external power unburdens the radio transmitter battery and maintains peak radiation levels throughout the mission.

🫡 We Are a Team of Veterans

We fully understand that the reliability of the control link is the foundation of any successful flight mission. Losing control of an aircraft due to interference or insufficient transmitter power means losing expensive equipment, which is why we take communication hardware selection seriously. We value the HPXGRC ELRS 2.4G 1W Micro TX Module for its true 1W output power at 2.4 GHz, which, combined with the ELRS protocol, provides a colossal margin of range and signal penetration. The active cooling fan prevents the board from overheating during summer heatwaves when the module runs at maximum capacity for extended periods, and the ability to supply power via a dedicated cable protects against sudden radio controller battery depletion at the most critical moment.

⚙️ Technical Specifications

Commentary / Comments

The primary advantage demonstrated by the HPXGRC ELRS 2.4G 1W Micro TX Module lies in its uninterrupted performance at extreme ranges, thanks to the high penetration capabilities of the ExpressLRS protocol. The ability to increase power to 1W allows operators to work confidently in zones with active electronic countermeasures where standard transmitters suffer from packet loss. The integrated screen significantly simplifies interaction with the device, allowing users to alter the refresh rate or output power without connecting to a computer or utilizing Lua scripts in the radio controller.

The Micro housing design fits precisely into the standard bays of most full-sized radio transmitters, ensuring a secure connection without play. The presence of a dedicated XT30 port for an external battery is an engineering necessity for kilowatt-level output, as it prevents voltage drops on the radio’s internal bus and guarantees a stable signal amplitude. The built-in cooler operates more quietly than competitors while effectively dissipating heat from the final amplification stage during intense utilization.

🎯 Target Audience / Suitable For

Military operators of reconnaissance and strike unmanned complexes receive uncompromising reliability of communication lines at extended distances from the ground control station. The 1W power output combined with the high noise immunity of ExpressLRS allows maintenance of control over the aircraft under complex electronic warfare conditions and when direct line-of-sight is obstructed by terrain features. The quick-configuration capability via the screen helps instantly adapt transmission parameters to specific mission requirements without wasting time. External power configuration ensures that the radio controller will not power down mid-flight due to excessive module energy consumption.

Engineers and builders of custom unmanned platforms developing long-range systems can utilize this module as a proven foundation for creating a reliable control loop. The standard SMA connector permits the attachment of a wide array of directional and omnidirectional antennas to optimize the radiation pattern for specific missions. Compatibility with open-source ELRS allows flexible firmware flashing and synchronization with a vast number of receivers from various manufacturers.

Sport pilots and Long Range explorers obtain an instrument for confident flights beyond visual line of sight without the fear of triggering emergency return-to-home modes due to signal loss. The minimal latency at high refresh rates provides filigree control precision at high speeds, which is essential when navigating complex tracks or maneuvering between obstacles. Active cooling ensures stable module operation during multi-hour training sessions in hot weather conditions.
