E108-GN04 GPS/BDS/GNSS module Multi-mode Satellite Positioning Navigation Module

[Communication interface]：UART

[Operating voltage]： 2.7-3.6V

[Positioning system]：BDS/GPS/GLONASS

[Communication protocol]： Support NMEA 4.11

[Product size]：9.7*10.5*2.4mm

[Introduction]：E108-GN04 is a high-performance, highly integrated, low-power, low-cost multi-mode satellite positioning and navigation module that supports GPS/BDS/GNSS/GALILEO satellite positioning. It has a small size, low power consumption, and SMD packaging. It can be used in GNSS positioning applications such as vehicle navigation, smart wearables, and drones. It also provides software and hardware interfaces that are compatible with other module manufacturers, and supports multiple ways to connect to other peripherals, greatly reducing the user's development cycle.
