Ebyte E108-GN03G-TTL AT6558R UART BDS/GPS/GLONASS Beidou Positioning Drones GNSS High-precision satellite positioning module

E108-GN03G-TTL GNSS multi-mode satellite positioning and navigation module BDS/GPS/GLONASS [Chip solution]：AT6558R [Communication interface]：RS232 [Operating voltage]： 2.7-5.5V [Positioning system:]：BDS/GPS/GLONASS [Product size]： 50.4*38.4*17.0mm [Introduction]：E108-GN03G-TTL 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 for GNSS positioning and navigation applications such as vehicle navigation, smart wearables, and drones. It supports BDS/GPS/GLONASS, is small in size, low in power consumption, and provides software and hardware interfaces compatible with other module manufacturers, greatly reducing 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.
