Chapter 1 Overview
1.1 Introduction
E108-GN02D is a high-performance, high-integration, low-power, low-cost multi-mode satellite
positioning and navigation module. It is small in size and low in power consumption. It can be used for
GNSS positioning such as car navigation, smart wear, and drone flight control. Application. Provides
hardware interface, supports UART communication and low power consumption mode. Support
BDS/GPS/GLONASS/GALILEO/QZSS/SBAS and other satellite positioning.
The module adopts the integrated design of radio frequency baseband antenna,
integrates DC/DC, LDO, radio frequency front end, low-power application
processor, RAM, Flash storage, RTC and power management, etc. It is powered
by button battery RTC and backup RAM. Reduce first positioning time. The
module supports serial port to connect with other peripherals, and the operation
is simple, and it will automatically start running after power on. Allow users to
get started very quickly.
