L76K GNSS Module for Seeed Studio XIAO
L76K GNSS Module for Seeed Studio XIAO is a compact, low-power multi-GNSS receiver offering global tracking through GPS, BeiDou, GLONASS, and QZSS. Built around the Quectel L76K chipset, it's designed to plug directly into the Seeed Studio XIAO series, making it well suited to asset tracking, robotics, and other location-aware projects.
Multi-GNSS Positioning
The module supports GPS, BeiDou, GLONASS, and QZSS, and is capable of both combined multi-system positioning and independent single-system positioning, giving you flexibility to balance accuracy, coverage, and power draw depending on your application.
Enhanced Reception
A built-in low-noise amplifier and surface acoustic wave filter improve sensitivity and reduce noise, while AGNSS support delivers faster, more precise fixes. The included high-performance active antenna is optimised for GPS L1 C/A, BeiDou B1, and GLONASS L1 frequencies for wide coverage and reliable signal reception.
High Precision Tracking
With 32 tracking channels and 72 acquisition channels, the module offers tracking sensitivity down to -162dBm and re-acquisition sensitivity of -160dBm, giving it strong performance even in weaker signal conditions.
Energy Efficient
Current draw sits at around 41mA during tracking and acquisition, dropping to just 360μA in standby, making it a practical choice for battery-powered or portable tracking devices.
Visual Fix Indicator
A small green LED provides visual confirmation of the 1PPS (one pulse per second) output once a fix is established, making it easy to confirm the module is working without needing to check the data output.
What's Included
- L76K GNSS Module board
