ATOMRC TX2500 VTX User Manual

The ATOMRC TX2500 is a powerful Video Transmitter (VTX) with 2.5W output. Its CNC case and fan help prevent overheating, while the LED segment display makes it easy to set and check the BAND/CH/POWER. It supports both X Band (5GHz) and Low Band frequencies.

Features

Supports X Band (5GHz) and Low Band frequencies.
CNC case and fan for efficient heat dissipation.
Adjustable power output: 800mW, 1600mW, 2500mW.
Wide voltage input range: 7V – 26V.
LED Segment Display for easy status checks of BAND, CH, and Power.
Button/IRC control for quick changes to CH and Power.

Notice

Users can choose either Button mode or IRC mode. If using Button mode, the IRC protocol must be disabled in Betaflight. In Button mode, the LED segment displays BAND/CH and power sequentially. In IRC mode, it displays frequency and power.
