Introduction

The E108-GN series is a high-performance, highly integrated, low-power, low-cost multi-constellation GNSS positioning module supporting BDS/GPS/GLONASS systems. The module features a compact footprint and low power consumption, making it suitable for applications requiring GNSS positioning. It adopts an RF-baseband integrated design, incorporating a DC/DC converter, LDO, RF front-end, low-power application processor, RAM, Flash memory, RTC, and power management unit. The module supports crystal oscillator or external pin clock input, and can power the RTC and backup RAM via a coin cell battery or farad capacitor to reduce TTFF. It offers multiple connectivity options with UART and GPIO interface support.
