Snapper 255

Snapper 255 Module

The Snapper 255 Single Board Computer Module is designed to be used as the system core in a wide range of ARM based products. It includes a high-performance ARM-based microcontroller (Marvell PXA255), a practical selection of peripherals, high-speed and flash memories and a powerful Altera FPGA; all integrated onto a single module no larger than a standard business card.

Snapper 255 incorporates a high-performance Marvell PXA255 ARM microcontroller at up to 400MHz, 64MB SDRAM, upto 512MB NAND Flash memory, 10/100T Ethernet MAC & PHY, 2x USB 2.0 OTG Host and USB 1.1 Device Ports, Serial UARTs, a selection of Altera FPGAs (EP1C4 or EP1C12), a stereo audio codec and touch-screen controller, and a versatile LCD controller. In fact, the Snapper Single Board Computer Module provides basically everything you need to create a high-end embedded system.

A buffered 32-bit ARM System Bus is also brought out to external pins, allowing it to be directly interfaced to other high-performance devices (i.e. a DSP). The FPGA external interface is implemented so as to support 32-bit or 64-bit Master/Target PCI at up to 66 MHz.

To aid product development with the Snapper Single Board Computer Module, Bluewater Systems has also released the Rig 200 Development Kit. These provide developers with a feature rich base board enabling the development of drivers and application software for products that are to use the Snapper 255 module. This is ideal for initial product prototyping and also allows software development to occur in parallel with hardware development.

Everything to get you started

A Rig 200 kit comes with Snapper 255, a fully configured Linux kernel with driver support, a carrier board with connectors for most peripherals and comprehensive doucumentation. Using this you can get started right away on prototyping your design, with the confidence that the software provided will work essentially unmodified in your final product design.

Tested and verified schematic designs are available for connecting various Snapper 255 peripherals to the outside world on your carrier board. Footprint and schematic files are available for some popular PCB design packages to help you get started.
