This GPS Module is a GNSS positioning device that provides accurate and consistent location data. It uses the ATGM336H navigation module powered by the AT6668 chip, providing precise satellite positioning even in tricky areas! It supports signals from multiple satellite systems, including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS. It can combine data from multiple systems for better accuracy or operate independently on a single system. Its strong anti-jamming capabilities make it reliable even in areas with interference. In weak signal areas, it can quickly gather a precise location position. The module comes with an external SMA antenna, which helps maintain stable signal reception. A dip switch allows you to easily switch between TX and RX communication pins for more flexible connections. It also includes a PPS (Pulse Per Second) signal output, which is useful for tasks requiring precise timing adjustments. You can use this module with the M5Stack Core, Core2 and the CoreS3.
