[Introduction]：E108-GN03D is a high-performance,highly integrated, low-power, low-cost multi-mode satellite positioning and navigation module. Based on the AT6558R solution, it can be used in vehicle navigation, smart wearables, drones and other GNSS positioning and navigation applications. It supports GPS/ BDS/GNSS/GLONASS, is small in size and low in power consumption, and provides software and hardware interfaces compatible with other module manufacturers, which greatly reduces the user's development cycle. It also supports multiple ways to connect to other peripherals, supports UART and GPIO interfaces, and can be customized if I2C and SPI interfaces are required.
