Adopting 3GPP Rel-17 RedCap technology, with features of URLLC/slicing, up to 256QAM DL/UL and LTE & NR-FR1 (20MHz), the module supports a theoretical peak data rate of 220Mbps in the downlink and 121Mbps in the uplink. The module supports LTE Cat 4 and 5G Sub-6 SA mode and is backward-compatible with Rel-15 and Rel-16 networks. The module is partially compatible with Quectel 4G EG2x/EC2x series 4G modules with smaller sizes, which can meet customers’ different application demands for medium speed, large capacity, low latency, high reliability, etc., and is convenient for customers to design. The RG255G series is an industrial-grade module, which can be widely used in smart grid, video network, internet of vehicles, POS machines, industrial automation, medium and low-speed FWA, and other scenarios. RG255G series module contains two variants: RG255G-NA and RG255G-GL. It can support RTOS systems of IoT devices with less RAM and flash memory. The module integrates a multi-constellation GNSS (GPS, GLONASS, BDS, and Galileo) receiver helping to simplify product design and achieve high-precision, fast, and dependable positioning. A rich set of Internet protocols, industry-standard interfaces (USB 2.0, PCIe 1.0, PCM, UART, SPI, 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. ## Product Brochure [Download Quectel_Product_Brochure_V8.6.pdf](https://www.quectel.com/content/uploads/2026/05/Quectel_Product_Brochure_V8.6.pdf) ## Documentation and resources ### Drivers - **Quectel_Android_RIL_Driver_aidl2_V4.7_EN** File Size: 2.01 MB [Login](https://www.quectel.com/login/?redirect=https%3A%2F%2Fwww.quectel.com%2Fproduct%2F5g-redcap-rg255g-series%2F) - **Quectel_Android_RIL_Driver_radio1.4_V4.0_EN** File Size: 2.30 MB [Login](https://www.quectel.com/login/?redirect=https%3A%2F%2Fwww.quectel.com%2Fproduct%2F5g-redcap-rg255g-series%2F) - **Quectel_Android_RIL_Driver_radio1.5_V4.0_EN** File Size: 2.36 MB [Login](https://www.quectel.com/login/?redirect=https%3A%2F%2Fwww.quectel.com%2Fproduct%2F5g-redcap-rg255g-series%2F) - **Quectel_Android_RIL_Driver_ndk_V4.0_EN** File Size: 1.62 MB [Login](https://www.quectel.com/login/?redirect=https%3A%2F%2Fwww.quectel.com%2Fproduct%2F5g-redcap-rg255g-series%2F) - **Quectel_Android_RIL_Driver_radio1.6_V4.5_EN** File Size: 2.39 MB [Login](https://www.quectel.com/login/?redirect=https%3A%2F%2Fwww.quectel.com%2Fproduct%2F5g-redcap-rg255g-series%2F) - **Quectel_Android_RIL_Driver_radio1.5_OemHook_V4.0_EN** File Size: 2.37 MB [Login](https://www.quectel.com/login/?redirect=https%3A%2F%2Fwww.quectel.com%2Fproduct%2F5g-redcap-rg255g-series%2F) - **Quectel_Android_RIL_Driver_aidl3_V4.7_EN** File Size: 1.75 MB [Login](https://www.quectel.com/login/?redirect=https%3A%2F%2Fwww.quectel.com%2Fproduct%2F5g-redcap-rg255g-series%2F) - **Quectel_Android_RIL_Driver_aidl1_V4.7_EN** File Size: 1.68 MB [Login](https://www.quectel.com/login/?redirect=https%3A%2F%2Fwww.quectel.com%2Fproduct%2F5g-redcap-rg255g-series%2F) - **Quectel_Windows_USB_Driver(M)_RNDIS_V1.8_EN** File Size: 25.70 MB [Login](https://www.quectel.com/login/?redirect=https%3A%2F%2Fwww.quectel.com%2Fproduct%2F5g-redcap-rg255g-series%2F) ### Hardware Development Resources - **Quectel_5G-REDCAP_EVB_User_Guide_V1.1** File Size: 2.77 MB [Login](https://www.quectel.com/login/?redirect=https%3A%2F%2Fwww.quectel.com%2Fproduct%2F5g-redcap-rg255g-series%2F) ### ToolKit - **QFlash_V8.0_EN** File Size: 326.70 MB [Login](https://www.quectel.com/login/?redirect=https%3A%2F%2Fwww.quectel.com%2Fproduct%2F5g-redcap-rg255g-series%2F) ## Related products - [YEGB001Q1A GNSS L1 + L5 adhesive + magnetic mount low profile active external antenna](https://www.quectel.com/product/yegb001q1a-active-gnss-magnetic-and-adhesive-antenna/) - [YF0020EA 5G adhesive mount FPC + cable dipole embedded antenna](https://www.quectel.com/product/yf0020ea-5g-fpc-antenna/) - [YSAN027XX DC~6GHz SMA female to IPEX MHF4L cable with an O-ring](https://www.quectel.com/product/ysan027xx-antenna-cable/) - [5G RedCap EVB kit](https://www.quectel.com/product/5g-redcap-evb-kit/) ## Also of interest - [5G RedCap RG255C series](https://www.quectel.com/product/5g-redcap-rg255c-series/) - [5G RedCap RG255C Mini PCIe series](https://www.quectel.com/product/5g-redcap-rg255c-mini-pcie-series/) - [5G RedCap RM255C-GL](https://www.quectel.com/product/5g-redcap-rm255c-gl/)
