Frequently Asked Questions

Q: Is this GPS Beidou GNSS Module compatible with Raspberry Pi and Arduino?

A: Yes! This module communicates via a standard UART/serial interface, making it fully compatible with all Raspberry Pi models (using GPIO TX/RX pins) and Arduino boards (Uno, Nano, Mega, etc.). It can also be used with ESP32, ESP8266, and other serial-capable microcontrollers.

Q: What satellite systems does this GNSS module support?

A: This module supports dual-mode GNSS, receiving signals from both the GPS (United States) and Beidou (China) satellite constellations simultaneously. Dual-constellation support improves positioning accuracy and reduces the time to first fix compared to single-system modules.

Q: What data format does the module output?

A: The module outputs standard NMEA 0183 sentences (e.g., $GPGGA, $GPRMC) via its serial interface. These are easy to parse using Python libraries (such as pynmea2 on Raspberry Pi) or Arduino-compatible GPS libraries, giving you latitude, longitude, altitude, speed, heading, and UTC time data.

Q: Does the module require any additional components to work?

A: The module is largely ready to connect — you just need to wire the TX, RX, VCC (3.3V or 5V depending on your board), and GND pins to your microcontroller. An external active GPS antenna may improve signal reception in indoor or obstructed environments, though many users find the onboard antenna input sufficient for outdoor use.
