GPS Module v2.1 with Antenna (ATGM336H)

The M5Stack Module GPS v2.1 is a high-performance GNSS module powered by the AT6668 chip, supporting GPS, BD2, BD3, GLONASS, GALILEO, and QZSS for precise, multi-system positioning with strong anti-interference and fast signal acquisition. It includes an external SMA antenna, DIP switch for TX/RX selection, and PPS output for time sync. Ideal for IoT, navigation, and automation, it now offers enhanced CoreMP135 compatibility and five UART pin options. M5Stack Module GPS v2.1 is a high-performance GNSS global positioning module that integrates the AT6668 high-performance chip to provide accurate and reliable satellite positioning services. The module supports multi-frequency and multimode GNSS signal reception and is compatible with multiple satellite navigation systems, including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS. It enables high-precision multi-system joint positioning or single-system independent positioning with excellent anti-interference capabilities. In weak signal areas, it can quickly obtain higher-precision location information. The module comes standard with an external SMA antenna. In addition, it features a DIP switch that allows flexible switching of TX/RX communication pins, and precise time synchronization via PPS signal output. It is suitable for high-precision positioning applications such as in-vehicle navigation, IoT positioning devices, remote monitoring, smart cities, smart home, and industrial automation. Compared with the previous Module GPS v2.0, this product has optimized interface compatibility to support CoreMP135, and the UART pin options have been increased from four to five. Features
