Overview
DarwinFPV VT5804 HV MAX is a 5.8G analog FPV video transmitter (VTX) with selectable output power up to 1W (1000mW). It is designed for higher efficiency and stable long-time 1W output, with protection circuitry to help reduce damage from reverse polarity wiring and high temperature. The power amplifier design is specified to tolerate operation even if the antenna is not connected.
Key Features
- Double protection: reverse polarity protection and over temperature protection
- Power amplifier design specified to prevent chip damage if the antenna is not connected
- Selectable output power: 200mW / 800mW / 1W (1000mW)
- Button/OSD parameter adjustment method
- SmartAudio VTX protocol support
- MMCX antenna interface
