1 Product overview
1.1 Product introduction
E108-GN series is a high-performance, high-integration, low-power, low-cost multi-mode satellite positioning and navigation module,
for BDS/GPS/GLONASS, small size, low power consumption, can be used for car navigation, smart wear, In the application of GNSS
positioning such as drones, it also provides software and hardware interfaces compatible with other module manufacturers, which greatly
reduces the user's development cycle.
The module adopts the integrated design of RF baseband, integrates DC/DC, LDO, RF front-end, low-power application processor,
RAM, Flash storage, RTC and power management, etc. It supports crystal oscillator or external pin clock input, which can be input through a
coin cell battery or farad capacitor powers the RTC and backup RAM to reduce the time to first fix. It also supports a variety of ways to
connect with other peripherals, and supports UART and GPIO interfaces. If you need I2C and SPI interfaces, please contact customer service
for customization.
1.2 Features
