Ai-Thinker GP-02 GPS Module Ultra Small GPS Development Board

The Ai-Thinker GP-02 GPS Module Ultra Small GPS Development Board is a compact GNSS receiver designed for integrating satellite positioning into electronic and embedded projects. It uses the AT6558R positioning chip and supports multiple satellite navigation systems including BDS, GPS, and GLONASS.

The module provides positioning information through a UART serial interface, making it convenient to connect with Arduino, ESP32, STM32, Raspberry Pi, and other systems capable of serial communication. NMEA data can be processed using a suitable GPS parsing library or custom software.

How To Use

1. Connect the module to a suitable regulated power supply according to the board's voltage requirements.
2. Connect TX and RX to the corresponding UART interface of your microcontroller or development board.
3. Place the module where it has a clear view of the sky for better satellite signal reception.
4. Use a serial monitor or compatible GPS parsing library to read NMEA positioning data.
5. Process the received data to obtain information such as latitude, longitude, altitude, and time.
6. For best reception, keep the ceramic antenna facing upward and away from large metal objects or other sources of interference.

Important Notes

• GPS/GNSS reception is generally better outdoors or in locations with a clear view of the sky.
• Satellite lock time can vary depending on environmental conditions and signal availability.
• Indoor operation, buildings, metal structures, and electromagnetic interference can reduce reception quality.
• Verify the module's required supply voltage before powering it.
• UART TX/RX voltage levels should be compatible with the connected controller.
• NMEA output must be parsed correctly by the host controller or software.
• Positioning accuracy can vary depending on satellite visibility, antenna placement, atmospheric conditions, and surrounding obstacles.
• Product specifications and board appearance may vary slightly between manufacturing batches.
