Hercules III EBX SBC with Atom CPU

EBX SBC with Intel Atom E-Series CPU, Integrated Autocalibrating Data Acquisition, and DC/DC Power Supply



Atom Based EBX SBC with DAQ

Hercules III is a high performance successor to the popular Hercules II EBX SBC. Combining processor, data acquisition, and power supply onto one board results in a thinner, lighter, more rugged, and easier to assemble embedded system. The 3-in-1 design addressed the needs of mobile and vehicle applications by offering the benefits of reduced size, weight, cost, and power consumption.

Hercules III combines all of the functionality of a single board computer with a complete analog and digital data acquisition circuit into a single board, offering the most functionality available in a small, compact form factor. The advanced data acquisition circuit features autocalibration and fully jumper-less configuration for maximum accuracy and reliable performance. The 1.6GHz Intel Atom E680T CPU offers an excellent price/performance, making Hercules III an ideal choice for a wide variety of embedded computing applications. Rugged on-board SDRAM memory offers provides better protection from shock and vibration than a SO-DIMM memory module.

Hercules III supports 1GB or 2GB of onboard SDRAM and provides high-resolution LVDS and VGA graphics interfaces. Additional I/O ports include SATA, CANbus, USB, serial, digital I/O, and Gigabit Ethernet. Flexible system expansion is based on stackable PC/104-Plus (ISA + PCI) modules. mSATA, PCIe MiniCard, and GPS modem sockets are provided for optional on-board storage and I/O.

Hercules III was designed with rugged applications in mind. From an operating temperature of -40°C to +85°C, the on-board rugged SDRAM, and its high tolerance for shock and vibration, Hercules III thrives in the most extreme environments.

Built-In Power Supply

Hercules III contains an on-board DC/DC power supply with 55 watts of output power. With approximately up to 20W required to power a fully loaded SBC, this leaves 35W available to power peripherals and add-on boards. The input range of +7-40VDC means that Hercules III is compatible with vehicle, battery, or industrial power sources and can be used in a wide range of applications without requiring a separate add-on supply. The on-board supply features ACPI compatibility for intelligent power management.
