4. When connecting to a computer using a USB-to-TTL tool, do not hot-swap the USB to

prevent serial port damage.

 Installation and Use

1. Fixed

Install and fix by yourself.

2. Power Supply

Use XT30 male connector. Power supply voltage: 12-34 V (maximum not exceeding 34 V),

recommended 28 V3A.

3. Positioning Data Connection

1) Connect the DuPont wire TTL serial port of this product to the GNSS serial port of the flight control.

Use the supporting data cable provided with the product to connect to the GNSS serial port of the flight control. Connect the end of the data cable labeled "TX" to the RX interface of the flight control, the end labeled "RX" to the TX interface of the flight control, and the end labeled "GND" to the GND interface of the flight control.

2)Use an SMA connection cable to connect the RF port of the product to the antenna port of the

UAV locator.

Note: Either the serial port or the RF port can be selected.

Interface with Flight Control Protocol

This product uses the ublox M10 receiver by default, and can output NMEA 0183 ASCII protocol or ublox protocol.
