M5Stack GPS Module v2.0 with External Antenna (AT6668)
Module GPS v2.0 is a high-performance GNSS global positioning module, featuring the ATGM336H navigation module from Zhaokong Microelectronics, integrated with the high-performance AT6668 chip to provide precise and reliable satellite positioning services. This module supports multi-frequency, multi-mode GNSS signal reception and is compatible with various satellite navigation systems, including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS, enabling high-precision, multi-system joint positioning or single-system independent positioning, and offering excellent anti-jamming capabilities. In weak signal areas, it can quickly acquire higher precision positioning information.
The module comes equipped with an external SMA antenna, and also features a dip switch to allow users to flexibly switch TX/RX communication pins, with PPS signal output for precise timing adjustments. It supports multi-stack usage, offering more customization and flexibility, making it suitable for high-precision positioning applications such as in-vehicle navigation, IoT positioning devices, remote monitoring, smart cities, and home and industrial automation.
