Description
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 multi-mode 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, 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.
