Notes
- 1. Do not install the receiver near heat sources, such as video transmitters or electronic speed controllers (ESCs), which generate significant heat.
- The 2.Gemini receiver has high power consumption. USB power alone may be insufficient; we recommend using the 5V supply from the flight controller's BEC instead.
- 3. To use Gemini mode, pair it with a high-frequency head that supports Gemini mode.
