Product description: Multi-GNSS positioning module for Seeed Xiao - L76K - GPS, BeiDou, GLONASS, QZSS - Seeedstudio 109100021
The L76K GNSS module designed for Seeed Xiao series offers multi-system positioning by supporting GPS, BeiDou, GLONASS and QZSS . Equipped with a ceramic active antenna and a low-noise amplifier (LNA) and SAW filter, it provides excellent sensitivity of -162 dBm and fast position acquisition (5.5 s AGNSS). With a UART interface supporting NMEA 0183 protocol, the module is easy to integrate with Xiao boards. Power consumption is only 41 mA in tracking mode and 360 µA in standby mode. The module is compact ( 18 x 21 mm ) and has a 1PPS LED indicator for synchronization signal. It is a perfect solution for GPS tracking, logistics and IoT projects.
The manufacturer has prepared a detailed user guide and instructions for connecting the L76K and Xiao GNSS module to Ubidots - check it out!
Multi-GNSS positioning module for Seeed Xiao - L76K - GPS, BeiDou, GLONASS, QZSS - Seeedstudio 109100021.

AGNSS function in L76K GNSS module
The L76K GNSS module supports AGNSS (Assisted GNSS), which significantly speeds up the positioning process, especially in difficult satellite reception conditions. With AGNSS assistance, the Time To First Fix (TTFF) is reduced to just 2 seconds for a hot start and 5.5 seconds for a cold start . This function uses external assistance data, which allows for faster finding and locating GNSS satellites. Combined with the built-in low-noise amplifier (LNA) and SAW filter , AGNSS increases the positioning precision and reliability of the module in various applications, such as navigation systems and IoT applications.
The module has a built-in low-noise amplifier and acoustic wave filter.
The module is equipped with a green LED that provides visual confirmation of the 1PPS output signal.
Connecting to Ubidots
After connecting the L76K GNSS Module with the Seeed Studio Xiao board, you can send location data (latitude and longitude) to the Ubidots IoT platform. The platform allows you to visualize the path on the map in real time by connecting the location points. This solution is ideal for object tracking, transportation monitoring, and location-based IoT systems.
Module Applications
- GPS Navigation in IoT Projects
- GPS Tracking Modules for Logistics and Transport Management
- Smart city projects with position monitoring
- Robotics and autonomous vehicles
- Location Systems for Resource Management
Attention!
Please pay special attention to the direction of the module installation. Do not connect it in reverse, as this may damage both the module and the Xiao board.
