Embedded board-maker Arcom has introduced its first SODIMM-sized single-board computer (SBC). The “Quantum” is based on a Marvell XScale PXA270 processor, and is available with an embedded Linux image preinstalled in onboard flash.

Arcom says the component-like Quantum SBC can eliminate “the work and risk involved in the more complex design elements associated with the processing core and operating system,” thereby allowing developers to focus on designing carrier boards containing application-specific functions and interfaces.

The board's PXA270 processor is clocked at either 312 or 520 MHz. Onboard memory includes 64 MB of SDRAM, 256 KB of SRAM, and either 32 or 64 MB of flash. Signals are also provided for interfacing with SD/MMC and CF cards. I/O interfaces include five serial ports, USB host and device interfaces, and an optional Ethernet piggyback module. A JTAG debug and test interface is also provided.

Arcom had not responded to LinuxDevices.com's inquiry regarding rumored Linux and Windows CE OS support for the Quantum by publication time. The company also reportedly offers a development baseboard for the SBC. The baseboard is said to support all of the Quantum's I/O, as well as various memory card and wireless device add-ons.

Pricing and availability information was not disclosed.
