The GNSS Add-on Module is a powerful and energy-efficient GPS solution made to bring high-precision positioning to your XIAO projects. Compatible with all XIAO development boards, this module supports multiple satellite systems, including GPS, BeiDou, GLONASS, and QZSS, providing reliable positioning in a variety of projects.
Powered by the Quectel L76K chip, it provides an improved reception with a built-in low-noise amplifier and surface acoustic wave filter, improving sensitivity and reducing noise for fast, accurate location tracking. With a high-precision 32/72 channel receiver, it has -162dBm tracking sensitivity and -160dBm re-acquisition sensitivity, which gives a strong performance in tough environments.
It is energy efficient, as it only consumes 41mA during tracking and just 360µA in standby mode, making it great for low-power projects. The integrated ceramic antenna provides a strong signal reception, outperforming traditional antennas.
A bright green LED indicates the 1PPS output when a GPS fix is established, providing easy visual confirmation. Whether you're building IoT devices, navigation systems, or other location-based projects, this GNSS Add-on Module will be a welcome addition to whatever you have planned next!
