Product Description
I491 series contains 2 variants: EG91-NAX and EG91-NAXD. I491 series is pin-to-pin compatible with Eagle I490, Eagle I4915Q as well as Quectel EG91, EG915Q and BG95 series modules. It is backward compatible with existing GSM/GPRS and UMTS/HSPA(+) networks, ensuring that it can be connected even in remote areas devoid of 4G network coverage.
A rich set of Internet protocols, industry-standard interfaces and abundant functionalities (USB serial drivers for Windows 8.1/10/11, Linux and Android, etc.) extend the applicability of the module to a wide range of M2M and IoT applications such as smart metering, wearable devices, environmental monitoring, asset tracking, fleet management, smart safety and alarm systems.
