Quectel has launched three smart single board computers (SBCs) to give developers more choice and speed up product development.

The QSM368Z, QSM560DR and QSM668SR are fully certified and offer options for connectivity, operating system and memory to suit different applications.

“These boards are fully finished hardware that can be easily integrated inside customers’ larger systems across a wide range of IoT use cases,” said Raymond Wang, head of smart SoCs at Quectel Wireless. “Provided in a ready-to-use, single, low-cost platform, these boards are helping simplify and accelerate the development process for IoT devices of all types, significantly reducing development time with rapid prototyping and cutting development costs.”

At the heart of the QSM368Z is the Rockchip RK3568 IoT processor, featuring a quad-core Arm Cortex-A55 CPU, Mali G52 GPU, 8M ISP HDR and 1Tops NPU. Together, these components balance computing, graphics and edge compute capabilities, helping developers run complex workloads, perform real-time data analysis and enable imaging applications directly at the edge.

The board supports Linux and Android, giving developers the flexibility to build on familiar, open platforms and speed up software development cycles. This dual OS support also ensures compatibility across a wide variety of commercial and industrial systems.

To enable rich media experiences and high data throughput, the QSM368Z includes triple-screen concurrent display support, 1000Mbit/s Ethernet and 4K video encoding. These are essential for modern use cases such as digital signage, industrial control dashboards and machine vision. The integrated NPU allows the board to run deep-learning algorithms, powering real-time decision-making for smart manufacturing and factory automation.

It includes built-in Wifi 5 and Bluetooth 4.2, along with optional support for Quectel LTE Cat 1, LTE Cat 4, Wifi 6 and GNSS modules. These options allow developers to tailor network performance and coverage for environments, from high-bandwidth industrial networks to remote or mobile IoT systems.

Engineered for reliability, it measures 120 by 100 by 22.25mm, weighs around 90g, and operates in temperatures from -10 to +75˚C, making it suitable for indoor and outdoor deployments where stability and durability are critical.

With its blend of computing power, flexible connectivity and rugged design, the QSM368Z provides a hardware foundation for IoT gateways, smart displays, industrial terminals, safety monitoring systems, NAS, NVR/DVR and automotive NVR.

The QSM560DR’s processing architecture provides the speed and responsiveness for applications that depend on high data throughput, low latency and multimedia performance. With 12Tops NPU and support for Ubuntu, Android and Windows, it gives developers flexibility to build products across industrial, commercial and consumer markets.

The platform’s multi-mode 5G capability supports NSA and SA networks, with 3G and 4G fallback, ensuring stable and consistent connectivity even in areas with variable coverage. In addition, Wifi 6E with DBS (dual band simultaneous) and 2×2 MU-MIMO technologies enables faster data transmission and greater network efficiency, essential for smart retail, industrial automation, robotics and safety monitoring.

By supporting downlink speeds up to 2.5Gbit/s on 5G NSA, the QSM560DR allows real-time transfer of high-resolution data, video and sensor information. The use of multiple antennas operating concurrently on the same frequency band reduces transmission errors and optimises throughput, for demanding environments where reliability and precision are key.

Measuring 120.5 by 106 by 22.5mm and weighing approximately 120g, it is designed for industrial-grade durability, operating within a temperature range of -35 to +75˚C.

With its blend of computing performance, multi-network connectivity and robust design, the QSM560DR provides a foundation for high-performance edge computing across sectors such as smart manufacturing, retail analytics, robotics and connected infrastructure.

Finally, again with support for Android, Linux and Ubuntu and featuring 1.1Tops NPU, the QSM668SR provides efficient processing and graphics performance for everyday edge computing needs, giving developers a flexible foundation for building and deploying customised smart products across diverse environments.

The QSM668SR supports multiple network modes, including LTE Cat 4, wifi, Bluetooth and GNSS, ensuring dependable connectivity wherever it is deployed. Under LTE Cat 4, the board achieves uplink speeds up to 150Mbit/s and downlink speeds up to 50Mbit/s, enabling stable data transmission for bandwidth-intensive applications. The inclusion of Bluetooth 5.0 and a range of wifi options further enhances wireless performance, supporting seamless device pairing and data exchange.

For applications requiring precise location tracking, optional GNSS functionality provides accurate positioning through GPS, Glonass, BDS, Galileo, QZSS and SBAS satellite constellations, suitable for fleet management, logistics and mobile industrial systems.

Designed with multimedia and peripheral interfaces, including HDMI, camera inputs, Ethernet, uart, USB, I²C, RS232, RS485, Can, SD and SIM, the QSM668SR supports a range of connected devices and sensors. This flexibility makes it suitable for use in IoT gateways, smart homes, industrial control terminals, retail, safety monitoring, vehicle equipment and logistics devices.

Compact and durable, it measures 102 by 100 by 23mm, weighs approximately 97.7g and operates from -20 to +75˚C, ensuring stable performance even in difficult environments.

In addition, Quectel provides a selection of antennas to complement its SBC and module platforms, ensuring reliable connectivity across cellular, wifi, Bluetooth and GNSS networks. For projects with unique requirements, Quectel (www.quectel.com) also offers custom antenna design and optimisation services.
