## Overview
Quectel RM255C-GL is a 5G Sub-6 GHz M.2 module. Adopting the 3GPP Rel-17 technology, the module supports a theoretical peak data rate of 223 Mbps in the downlink and 123 Mbps in the uplink. The module supports LTE Cat 4 and 5G Sub-6 GHz SA mode, and is backward compatible with Rel-15 and Rel-16 networks.

With M.2 form factor, It is pin-to-pin compatible with Quectel 5G modules RM5x0N/ RM50xQ, and is pin-to-pin and size compatible with LTE-A Cat 6 module EM06, Cat 12 modules EM12/ EM12xR/ EM120K, Cat 16 module EM160R-GL and 4G module EM05.

RM255C-GL supports Qualcomm® IZat™ location technology Gen 9VT (GPS, GLONASS, BDS, Galileo, QZSS and NaVIC*). The integrated GNSS receiver greatly simplifies product design and provides quicker, more accurate and more dependable positioning capability.

A rich set of Internet protocols, industry-standard interfaces (USB 2.0, PCIe 2.0, etc.) and abundant functionalities (USB drivers for Windows 10/ 11, Linux and Android) extend the applicability of the module to a wide range of RedCap applications.
