SBC QSM-board QSM668SR-WF 4+64GB

The SBC QSM-board QSM668SR-WF 4+64GB is an SBC QSM-board based on the SC668S-WF smart module and the QCM6125 platform. It is designed for embedded and edge applications that need to combine compute performance, multimedia capability, local wireless connectivity, and broad peripheral integration on a compact platform. With 4 GB RAM and 64 GB storage, this version is positioned for more demanding SBC-class Linux and Android application workloads.

QCM6125 platform for embedded multimedia and edge computing

The platform is built around a Qualcomm 64-bit octa-core Kryo 260 processor with integrated Adreno 610 GPU and a 1.1 TOPS NPU. This makes the board suitable for edge computing tasks, multimedia processing, HMI concepts, and AI-adjacent embedded workloads that go beyond classic MCU-level functionality.

WF variant within the QSM668SR family

Within the QSM668SR family, the QSM668SR-WF is the variant focused on Wi-Fi and Bluetooth. This is important for product positioning because the next product, QSM668SR-EM 4+64GB, is based on the SC668S-EM and therefore addresses the LTE Cat 4 configuration within the same family. For projects without a cellular requirement, the WF version is the more focused platform.

Broad interface base for product-oriented integration

The QSM668SR platform integrates a broad peripheral and multimedia base including USB, Ethernet, RS232, RS485, CAN, HDMI, MIPI CSI, SIM, and SD. In addition, the underlying SC668S series lists camera, touch, UART, I2C, I2S, and SPI connectivity. This makes the board suitable for development tasks where display, sensors, communication, and control need to converge on one application platform.

Suitable for IoT, robotics, and smart embedded systems

The platform is positioned for use cases such as intelligent robots, IoT gateways, smart home, industrial equipment terminals, smart commercial displays, smart cash registers, vending machines, and other M2M and edge designs. Support for Android, Linux, and Ubuntu allows the board to fit into a wide range of embedded software stacks.
