Quectel QSM668SR | Full-Featured ARM Platform Supporting LTE, Wi-Fi and Bluetooth

The Quectel QSM668SR is a full-featured ARM platform designed to simplify the development of connected, intelligent devices. It combines local computing, multimedia capability, and multi-mode wireless connectivity on a single board, making it suitable for projects that need more than basic sensing or communication, yet do not require an overly complex hardware architecture.

Built around a capable multi-core processor with integrated graphics and AI acceleration, the platform can handle interactive interfaces, video processing, edge inference, and real-time device coordination. It supports multiple operating systems, including Android, Linux, and Ubuntu, giving developers flexibility to choose the software environment that best fits their application, user experience goals, and long-term maintenance strategy.

The QSM668SR series is an LTE Cat 4 intelligent product based on the QCM6125 eight-core 64-bit processor, supporting multiple network modes and a built-in Qualcomm Adreno™ 610 GPU. It is compatible with Android, Linux, and Ubuntu operating systems. The QSM668SR series products deliver excellent performance and powerful multimedia functions.

What sets the QSM668SR apart is its broad integration of wireless technologies. With LTE, Wi-Fi, and Bluetooth support, it can serve as a central hub that connects to cellular networks, local wireless infrastructure, and nearby peripherals simultaneously. This makes it especially useful for IoT gateways, smart robots, industrial terminals, digital signage, retail devices, vehicle equipment, and information collection systems that must operate reliably in mixed network environments.

The platform also provides rich peripheral interfaces, allowing direct connection to displays, cameras, sensors, Ethernet networks, serial devices, and other industrial or consumer components. This high level of integration helps reduce the need for additional expansion boards and accelerates the path from prototype to production-ready design.

The QSM668SR series integrates rich external interfaces — HDMI, camera, video UART, USB, Ethernet, I2C, RS232, RS485, CAN, SD, and SIM cards — greatly expanding the application scenarios in the M2M industry, including:

• Smart robots
• IoT gateways
• Smart homes
• Industrial equipment terminals
• Smart business displays
• Smart cash registers
• Smart security systems
• In-vehicle devices
• Information collection devices
• Vending machines
• Logistics cabinets
