Reyax RYS3520_LITE GNSS Antenna Module Lite Evaluation Board DIP Version

Connect the board's VCC and GND pins to the Arduino's 3.3V and GND pins respectively. Then, link the board's TX pin to an RX pin on the Arduino (e.g., digital pin 2 for SoftwareSerial) and the board's RX pin to an Arduino TX pin. Use a serial library in your Arduino sketch to read the NMEA sentences output by the GNSS module. Ensure you are using a 3.3V-compatible Arduino or a logic level converter.

The module outputs standard NMEA 0183 sentences over its UART interface at a default baud rate (commonly 9600 or 115200 bps—check the datasheet). You can use libraries like TinyGPS++ for Arduino or pynmea2 for Python on Raspberry Pi to parse these sentences. The library will extract useful data such as latitude, longitude, altitude, speed, course, number of satellites, and fix status, converting them into readable variables for your application.

The RYS3520_LITE board features an integrated patch antenna designed for general use. For connecting an external active antenna, you would typically need the full RYS3520 module version which includes a dedicated RF input connector (like an IPEX or SMA). This Lite evaluation board is intended for basic testing with its built-in antenna. For projects requiring an external antenna for better reception, consider using the standard RYS3520 module directly.
