Introduction

The E108-GN03 series is a high-performance, highly integrated, low-power, low-cost multi-constellation GNSS positioning module supporting BDS/GPS/GLONASS. Compact in size and power-efficient, it is suitable for applications such as in-vehicle navigation, smart wearables, and UAVs. It provides software and hardware interfaces compatible with other module manufacturers, significantly reducing customer development cycles.

The module adopts an RF-baseband integrated design, incorporating DCDC, LDO, RF front-end, low-power application processor, RAM, Flash storage, RTC, and power management. A coin cell battery or supercapacitor can supply power to the RTC and backup RAM to reduce TTFF. It also supports multiple interface options for connecting to external peripherals, including UART, GPIO, RS232, and RS485. For I²C, SPI, or USB interfaces, please contact customer support for customization.
