The L76K GNSS Module for XIAO offers high-precision multi-GNSS positioning with an LNA, a SAW filter, a ceramic antenna and low power consumption. It is designed to fit with Seeed Studio XIAO boards, so you can add location to a very small project.
It supports GPS, BeiDou, GLONASS and QZSS. The position accuracy is 2.0 m CEP, velocity accuracy is 0.1 m/s and timing accuracy is 30 ns.
The receiver has 32 tracking and 72 acquisition channels, with acquisition sensitivity of -148 dBm, re-acquisition of -160 dBm and tracking of -162 dBm. Cold starts take about 30 seconds without AGNSS and about 5.5 seconds with it, while hot starts take 5.5 seconds without and 2 seconds with AGNSS. The update rate is 1 Hz by default and up to 5 Hz. It talks NMEA 0183 and the CASIC protocol at 9600 to 115200 baud, and the board measures 18 x 21 mm.
The package includes the module, an active antenna with an iPex connector and two 7-pin 2.54 mm female headers. For the fastest first fix, use the module outdoors with a clear view of the sky.
Makers building wearable trackers, small loggers and IoT nodes on the XIAO platform.
Solder the headers so the module sits flat on the XIAO board, connect the active antenna to the iPex connector and read the NMEA sentences on the serial port at 9600 baud. Try the module outdoors first, and give it a minute for the first fix. If you plan to run on a battery, use the standby mode between position reports.
