The SC668S series is Quectel’s new generation of multi-mode LTE Cat 4 smart module with built-in Android 10/11/13 OS. Based on QCM6125 high-performance 64-bit octa-core processors with built-in Adreno 610 GPU, it is an ideal solution for a wide range of industrial and consumer applications requiring high data rates and multimedia functions. The SC668S series comes in five variants: SC668S-CN, SC668S-EM, SC668S-NA, SC668S-JP and SC668S-WF (only supports Wi-Fi and Bluetooth).

The SC668S series supports multiple-input multiple-output (MIMO) technology. The concurrent use of multiple antennas at the receiver end on the same frequency band greatly minimizes bit error rate and optimizes the data speed, thereby improving communication quality. The module also supports multi-constellation GNSS (GPS, GLONASS, BDS, Galileo, QZSS and SBAS) receiver for fast and accurate positioning.

A rich set of interfaces (such as LCM, camera, touch panel, UART, USB, I2C, I2S and SPI) are integrated allowing the module to serve a wide range of M2M applications, including smart cash registers, smart POS, smart safety, on-board equipment, high-end information acquisition equipment, smart robots, smart home, smart hardware, industrial smart handheld equipment, audio and video recorders, smart interphones, smart wearables, vending machines, logistics cabinets, etc.
