Introduction

The E108-GN series is a high-performance, highly integrated, low-power, low-cost multi-constellation GNSS positioning module supporting BDS/GPS/GLONASS. With its compact form factor and low power consumption, it is suitable for applications such as vehicle navigation, smart wearables, and UAVs. It also provides software and hardware interfaces compatible with other module vendors, significantly reducing users' development cycles. The module adopts an RF-baseband integrated design, incorporating DC/DC, LDO, RF front-end, low-power application processor, RAM, Flash storage, RTC, and power management. It supports crystal oscillator or external pin clock input, and can power the RTC and backup RAM via a coin cell battery or supercapacitor to reduce TTFF. Multiple connectivity options are supported, including UART and GPIO interfaces. For I2C or SPI interfaces, please contact customer service for customization.
