BeastFPV 2.1 ELRS TX 2.5W transmitter

Buy power beyond the pale with the BeastFPV 2.1 ELRS TX 2.5W Transmitter!

This is a unique RF module for ultra-long-range communication using the ExpressLRS protocol. The BeastFPV 2.1 ELRS TX model produces a record 2.5 Watts of output power. The 2.1 GHz frequency provides the perfect balance of speed and penetration. You get communication where conventional transmitters are powerless.

• Record output power up to 34.47 dBm or 2.5 Watts of clean signal.

• Unique 2.1 GHz frequency with high penetration and low latency.

• Dual-chip ESP32 + ESP8285 architecture for maximum performance.

• Active cooling fan for stable operation at maximum power.

• Compatible with Radiomaster, Jumper and other OpenTX/EdgeTX remotes.

Technical excellence and unique frequency

The BeastFPV transmitter operates in the rarely used 2.1 GHz band. This is a frequency between the standard 2.4 GHz and 900 MHz. It provides better diffraction than 2.4 GHz and lower latency than 900 MHz. The signal confidently skirts the forest and penetrates concrete walls.

The heart of the module is two powerful microcontrollers ESP32 and ESP8285. This combination ensures lightning-fast packet processing and a stable radio path. The ExpressLRS protocol operates at packet rates up to 1000 Hz. Control latency is only 2-5 milliseconds.

The output power of 2.5 W is an absolute record for compact modules. The line-of-sight communication range exceeds 50 kilometers. In urban areas, reliable reception reaches 10-15 kilometers. The signal breaks through several reinforced concrete floors.

Design, Cooling and Compatibility

The module has ultra-compact dimensions of 55×39×11 millimeters. The weight of the device is only 9.2 grams. The SMA connector allows you to connect any external antennas. The design is optimized for installation on the rear panel of the remote control.

The main engineering feature is the built-in cooling fan. At power levels above 500 milliwatts, active cooling is required. The fan automatically turns on when the threshold temperature is reached. This guarantees stable power without overheating or signal degradation.

The module is powered by voltage from 5 to 24 volts DC. Recommended range is 2S-4S LiPo batteries. Due to high power, a separate power supply is required. The built-in stabilizer provides clean power to the RF path.

The module is fully compatible with most OpenTX and EdgeTX remotes. Integrates especially well with Radiomaster TX12, Jumper T12, T16, T18. Fastening is carried out through standard holes or double-sided tape. Connection to the uplink port of the remote control is made using the included cable.

Operation and Application

This is the solution for ultra long range missions. The transmitter is in demand by pilots exploring mountains and remote regions. The drone maintains communication over tens of kilometers. The 2.5 W power allows you to fly over the sea and deserts without losing control.

The delivery set includes the module itself and a high-quality antenna. All components undergo individual testing. The device is ready for use immediately after connection and configuration
