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.

Data Acquisition Circuit

Hercules III includes a complete autocalibrating jumper-less analog and digital I/O circuit equivalent to our top-of-the-line PC/104 board. It contains 32 analog inputs with 16-bit resolution and 250KHz sample rate, backed by a 2K-sample FIFO with programmable threshold. Programmable input ranges from a wide-range +/-10V down to 0-1.25V are provided. The analog circuitry also includes 4 D/A channels with 12-bit resolution and jumperless output range selection and simultaneous update capability. On the digital side, in addition to the standard 40 digital I/O lines with programmable direction, Hercules III’s DAQ circuit adds two counter/timers for A/D sample rate control, pulse counting, frequency generation, or other applications. Its advanced control logic has more features and flexibility to fit almost any application, such as internal/external A/D clock source, scan and single-sample modes, and our exclusive programmable FIFO threshold that lets you tune the board’s performance to your application. Also four independent programmable Pulse-Width Modulation outputs (PWM) are available to users. The data acquisition circuit is fully supported by our Universal Driver software for a wide range of operating systems. The Hercules III data acquisition circuitry is identical to that of Hercules II, preserving backward compatibility.
