Technical Specifications

Pinouts

Connection with Flight Control

• PixHack: Radio Interface Plugged into Flight Control
• Pixhawk: plug into the flight controller’s telem1 or telem2 interface
• V5+/v5 nano/X7/X7 PRO/NORA ： Green connector is connected flight controller, white connector is connected to digital transmission

Ground Station Connection

For Mission planner

Please select 57600 baud rate when connecting. Note whether the driver is installed correctly and whether the port number is selected.

For QGroundcontrol

It should automatically connect after being recognized by QGroundcontrol.

P900 Configuration

The P900 has already been configured at the factory. Generally, you do not need to configure this document. If you have requirements, you can configure it according to the instructions below.

Configuration Mode Enable

Use the USB cable to connect the P900 data transmission to the computer, open the serial assistant software, press and hold the CONFIG and RESET buttons, release the reset button, then release the CONFIG button. The serial assistant pops up the “NO CARRIER ok” prompt to enter the configuration mode.

Configuration mode interface baud rate is fixed 9600 If a late configuration error occurs, it can be reconfigured through the configuration mode.
