  • 2pins connector for power supply(5V,1A)
  • 6pins connector,UART and Power out for connected device
  • SMA Antenna connector
  • Build-in radio module (800-2000m,3DR compatible)
  • RTK module,support all GNSS constellation
  • ESP32-S module for WiFi,CPU,UART
  • Bluetooth module(rear side)

Both USB and 2pins support power in, only choose one

USB plugged in the computer’s USB port may not work


  • WiFi (2.4G b/g),connect WiFi to fetch RTCM data from remote NTRIP caster or upload RTCM data to NTRIP caster
  • Bluetooth (2.1 EDR+4.0),output NMEA or RTCM data
  • Radio(800-2000m,3DR compatible)

Quick guide



1.Connect usb interface to USB adapter or Power bank. the Current must exceed 300mA.

2.the Power LED red light will be on.

3.Press “Scan” to find your local WiFi or the hotspot created from your Phone.

above “192.168.xx.xx” is your new IP address, please remember it.

NTRIP client information

  1. Please config the NTRIP client account.
  2. if your reference station is VRS, please config NMEA relay back.

Please “Submit” to save the configuration.

Then the device will reboot to apply the new configuration.

In the next, you only need power on the device, It will work properly.

Android app for test

Download app from the following url:


1.Paired BT in your phone. (BT name:ET10_SPP……)

2.open app, choose the paired BT in the preference

3.start or stop connection

4.tap “start” in logging to log nmea data

Output NMEA to other devices

6pins UART connector support output NMEA data. the 6pins definition is printed near connector.

6pins connector specification: Pitch 1.25mm BAR Connectors
