The cExpress-BT2 is a COM Express COM.0 R2.1 Type 2 module supporting Intel Atom processor E3800 Series and Intel Celeron N2930/J1900 processor SoC (codename: Bay Trail).

The cExpress-BT2 is specifically designed for customers who need high-level processing and graphics performance with low power consumption in a long product life solution.

The cExpress-BT2 features Intel Atom processor E3800 and Intel Celeron N2930/J1900 processor supporting non-ECC type DDR3L dual-channel memory at 1066/1333 MHz to provide excellent overall performance. Integrated Intel Gen7 HD Graphics includes features such as OpenGL 3.1, DirectX 11, OpenCL 1.1 and support for H.264, MPEG2, VC1, VP8 hardware decode. Graphics outputs include DDI ports supporting HDMI/DVI/DisplayPort and single-channel 18/24-bit LVDS (eDP is optional). The cExpress-BT2 is specifically designed for customers with high-performance processing graphics requirements who want to outsource the custom core logic of their systems for reduced development time.

The cExpress-BT2 has soldered type non-ECC DDR3L memory for up to 4 GB. In addition, onboard eMCC memory (8/16/32GB) and SDIO signals are optionally supported.

The cExpress-BT2 features a single onboard Gigabit Ethernet port, USB 3.0 ports and USB 2.0 ports, and SATA 3 Gb/s ports. Support is provided for SMBus and I2C. The module is equipped with SPI AMI EFI BIOS, supporting embedded features such as remote console, CMOS backup, hardware monitor, and watchdog timer.

The ADLINK cExpress-BT2 computer-on-module with built-in SEMA Cloud functionality is ready-made for Internet of Things (IoT) applications. The cExpress-BT2 is able to connect legacy industrial devices and other IoT systems to the cloud, extract raw data from these devices, determine which data to save locally and which to send to the cloud for further analysis. The results these analyses can provide valuable information for policy decision making and generate innovative business opportunities.
