CAPA84R – 3.5″ Embedded SBC with Intel® Celeron® Processor


3.5″ Embedded SBC with Intel® Celeron® Processor J1900/J1800, LVDS, VGA, DisplayPort, Three GbE LANs and Audio.

CAPA84R, is a fanless 3.5-inch embedded motherboard powered by the Intel® Celeron® processor J1900 quad-core or J1800 dual-core. The CPU is located at the rear side of the motherboard, which further aids the heat-extraction process and simplifies maintenance procedures. This fanless embedded board was designed for operational efficiency in rugged architecture with a wide operating temperature range of –20°C to +70°C. The CAPA84R also comes with rich I/O connectors, stunning graphical performance and an emphasis on expandability, making it a performance-driven solution for Industrial IoT and M2M related applications.

The CAPA84R supports one 204-pin DDR3L-1333 SO-DIMM socket with up to 8GB of system memory. There are also one SATA-300 port and one M.2 Key B supporting SATA for storage. The 3.5-inch embedded SBC with the Intel® integrated Gfx graphics is made to bring a true high definition visual experience with dual display configurations through the DisplayPort, 18/24-bit dual-channel LVDS and VGA.

We have dedicated ourselves to developing first-rate embedded boards to ensure all clients get the best value from our products. The industrial-grade CAPA84R provides enhanced computing capability, excellent graphics yet low power consumption to serve the needs of diverse industrial IoT applications,” said Michelle Mi, a product manager of ECSE Division at Axiomtek. “With the impressive graphical performance, the CAPA84R provides an ideal solution for customers seeking performance demanding digital signage or infotainment system applications. The 3.5” motherboard also has three Gigabit Ethernet ports and one USB 3.0 port which support industrial cameras for machine vision applications.

Furthermore, this 3.5-inch embedded board adopts a rich array of I/O interfaces including two USB 2.0 ports, one USB 3.0 port, three Gigabit Ethernet ports with Intel® Ethernet controller i211-AT, one RS-232/422/485 port, one RS-232 port, HD Codec audio port and 8-in/out DIO port. The CAPA84R is expandable with one M.2 Key E connector supporting PCIe x1 interface for Wi-Fi modules and one M.2 Key B connector supporting USB 2.0 interface for cellular modules. The 3.5″ embedded SBC also utilizes advantages of watchdog timer and hardware monitoring features to ensure reliable operation. Moreover, the CAPA84R runs on 12V DC power, supporting auto power-on function.
