Pololu LOCOSYS LS20031 66-Channel GPS Receiver Module (MT3339 Chipset)

The LOCOSYS LS20031 GPS receiver module is a compact and efficient solution for high-precision navigation needs. Supporting 66 channels, it provides GPS data through various NMEA sentences at a rate of up to 10 Hz. With an integrated ceramic antenna, this module eliminates the need for additional external antennas, simplifying installation and reducing costs. It boasts rapid satellite acquisition, achieving a cold start fix in 32 seconds and a hot start fix in less than 1 second.

Ideal for a wide range of applications, this GPS module can be used in drones, robotics, and other projects requiring precise location tracking. Its ability to support assisted GPS (AGPS) and self-generated ephemeris prediction ensures consistent performance even in challenging environments. The built-in rechargeable battery preserves system data, facilitating rapid satellite acquisition upon startup.

The LS20031 is designed for ease of use with a 3 to 4.3 V operating range, making it compatible with various systems. The red LED indicator provides a clear visual cue for GPS fix status, enhancing user experience. Its compatibility with QZSS and SABS systems like WAAS, EGNOS, MSAS, and GAGAN further extends its global usability.

Configuration is straightforward, with the module initially set to a 5 Hz update rate and a 57600 bps serial communication rate. Users can easily adjust settings using the Mini GPS Windows application, allowing customization of baud rates and NMEA sentence outputs. This flexibility makes the LS20031 an adaptable choice for both hobbyists and professionals seeking reliable GPS data integration.

Note: The LS20031 is a 3.3 V device, requiring external components for interfacing with 5 V systems. It replaces the older model with the MT3329 chipset, offering improved performance and features.
