Product Features

Supports operation across the 4.9G to 6.1G broadband spectrum
Button/IRC control for quick CH and power adjustment
Special design eliminates antenna connection and power amplifier burnout
Automotive-grade RF crystal with temperature range and enhanced frequency stability
Fully metal CNC casing with dustproof and explosion-proof features, excellent heat dissipation, and stable power output
Fast frequency locking, no interference with peers during startup
High-temperature protection: When the product overheats during continuous operation, the image transmission system activates power reduction protection. Once the system reaches the equilibrium point, power output gradually increases to prevent thermal damage from high temperatures.
High output power, stable output power, and long transmission distance

Interface Function Definition

joggle functional description
GND1,GND2: The ground wire connects to the GND of the flight control system.
RX:

Image transmission control signal input: Connect to the UART TX interface of devices such as flight control systems, and activate the IRC control protocol to regulate functions including transmission frequency, bandwidth, and power.
VTX: Video input: Connect to the flight control's video output (VTX)
VCC: Connect the DC 7V-20V power input to the positive terminal of the DC-DC buck regulator module, not directly to the flight controller.
GND: Connect the negative terminal of the power input to the negative terminal of the DC-DC buck regulator module.
POWER:

power adjustment button

  • Short press to adjust power, cycling between five levels: 25mW, 500mW, 1W,5W, and 10W.
  • Double-click to enter PIT mode (Maintenance Mode, with minimal video output power; avoid activation if possible).
  • Long press to lock/unlock the image transmission power and frequency buttons (to prevent accidental touches)
FRCH:

Frequency/Channel Adjustment Button

  • Short press to change channel, cycling between CH1 to CH8
  • Long press for 3 seconds to enter frequency group switching mode. Short press again to change the frequency group.
PWR LED:

Power indicator: Red (flashes to indicate power level)

  • Red light off: indicates entry into PIT mode
  • Red light on: Locks the video transmission power and frequency buttons
CH LED: Channel indicator: Green (indicates channel CH by the number of flashes)
FR LED: Band indicator light: Blue (indicates the number of flashes for the band)
