Tiny module targets mobile, embedded apps

Sep 14, 2007 — by LinuxDevices Staff — from the LinuxDevices Archive — views

Embedian has started shipping a tiny embedded processor module available with Linux and a development board with LCD. Roughly half the size of a credit card, the COM-7211 is based on an ARM9 processor, and targets industrial automation, portable devices, POS, transportation, medical, and defense applications.

The COM-7211 measures 1.6 x 2 inches (4 x 5 cm). It is based on a Samsung S3C2400A ARM9 processor clocked at 400MHz, and includes 64MB of SDRAM and 64MB of NAND flash, expandable via CompactFlash interface signals.

A 200-pin board-to-board connector provides the signals for I/O expansion, which include Ethernet, USB host and device interfaces, three serial ports, LCD, audio, IIC, SPI, and GPIOs. A JTAG debug and test interface are also provided.

Additionally, Embedian says that the “full 32-bit wide CPU bus is available for custom extensions.” The board takes 5V power, drawing a max of 1.6 Watts and a minimum of 800 milliwatts, according to the company.

The COM-7211 is shipping now, preinstalled with a Debian ARM filesystem and Linux kernel. Another available OS option is Windows CE 5.0.

Pricing was not disclosed.
