## Overview
Quectel RG660QB is a series of 5G LGA modules optimized specially for IoT and eMBB applications. Adopting the 3GPP Rel-18 technology, it supports both 5G NSA and SA modes with Option 3x/ 3a/ 3 and Option 2 network architectures, and is backward compatible with the 4G/ 3G networks. The module is designed to meet varying customer application demands such as high speed, large capacity, low latency, and high reliability.

RG660QB series modules are industrial-grade, for industrial and commercial applications only.

The RG660QB series supports Qualcomm® IZat™ location technology Gen9C Lite (GPS, GLONASS, BDS, Galileo, and QZSS). The integrated GNSS receiver greatly simplifies product design and provides a quicker, more accurate, and more dependable positioning capability.

A rich set of internet protocols, industry-standard interfaces (USB 2.0/3.0/3.1, PCIe 3.0, PCM, UART, etc.) and abundant functionalities (USB drivers for Windows, Linux, and Android) extend the applicability of the module to a wide range of IoT and eMBB applications, such as business routers, home gateway, STB, industrial laptops, consumer laptops, industrial PDA, rugged tablet PCs, and video transmission.
