Introduction

The E108-GN04 series is a high-performance, highly integrated, low-power, low-cost multi-constellation GNSS positioning module supporting BDS, GPS, GLONASS, and GALILEO satellite systems. The module features an RF-baseband integrated design, incorporating a DCDC converter, LDO, RF front-end, low-power application processor, RAM, Flash memory, RTC, and power management unit. It supports powering the RTC and backup RAM via a coin cell battery or farad capacitor to reduce TTFF. The module offers multiple interface options including UART, GPIO, RS232, and RS485, along with active antenna detection and protection. Its compact design and low power consumption make it suitable for a wide range of applications requiring GNSS positioning, while its hardware and software interfaces are compatible with modules from other manufacturers, helping to shorten development cycles.
