M5Stack GPS Unit - GPS module with AT6558 chip

Description

The M5Stack GPS Unit is a module with the AT6558 GPS chip, designed for the M5Stack sets. The AT6558 is a 56-channel GNSS receiver. The system can receive data from the main positioning systems: GPS, GLONASS, BDS, Galileo, QZSS and SBAS. Determining the position with the help of the module allows you to achieve an accuracy of up to 2.5 m. The module is characterized by high sensitivity, low static drift, low power consumption and compact size. The built-in antenna is connected to a dedicated MAX2659 amplifier, thanks to which the signal is stable. The module is perfect for applications in navigation and monitoring of vehicles or in portable devices. It communicates via the UART interface (Grove connector). Full documentation is available on the product page.
