M5Stack GPS Unit v1.1 (AT6668)

GPS Unit v1.1 is a GNSS global positioning navigation unit, integrating the high-performance CASIC navigation chip AT6668 and signal amplifier chip MAX2659, with a built-in ceramic antenna, providing more precise and reliable satellite positioning services. Compared to previous products, AT6668 supports multi-frequency and multi-mode GNSS signal reception, receiving signals from multiple satellite navigation systems (including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS), supporting multi-system combined positioning as well as single-system standalone positioning. It has enhanced anti-interference capability and higher positioning accuracy, allowing it to quickly acquire high-precision location information in areas with weak signals. This module is widely applicable in high-precision positioning applications, such as in-vehicle positioning and navigation, IoT positioning devices, and more. Features Supports multiple satellite navigation systems (GPS/QZSS/BD2/BD3/GAL/GLO) Multi-frequency and multi-system reception Multi-channel Low power consumption 2x LEGO-compatible holes Programming platforms: Arduino, UIFlow, etc. Contents 1x Unit-GPS v1.1 1x HY2.0-4P Cable (20CM) Applications In-vehicle positioning and navigation Wearable devices IoT positioning devices Drones Portable devices Public transportation station reporting
