Blue Chip's RE1 is a small (3.93 x 2.75 inches) SBC that targets HMI designs. According to the company, the device can drive displays of up to 480 x 272 pixel resolution via off-the-shelf "personality modules" -- see later in this story -- or support custom screen choices of up to 800 x 600 pixels.

The company says the RE1 runs Windows CE 6.0 via RMI's MIPS32-based Alchemy Au1100, using 1.5 Watts when clocked at 333MHz or 2 Watts when clocked at 500MHz. The device's low power dissipation figures make it a candidate for being operated via POE (Power Over Ethernet), courtesy of its standard 10/100 Ethernet port, says Blue Chip.

According to Blue Chip, the RE1 holds 64MB of soldered-on RAM, and 32MB of NAND flash memory (64MB of flash is a factory option). On the bottom of the SBC, and thus not visible in the photo at the top of our story, are Compact Flash and SD expansion slots, allowing storage to be added.

The RE1 has a connector at board's edge that can accept DV input power ranging from 7V to 36V, and its other "real-world" connectors include a USB 1.1 client, two USB 1.1 hosts, and the Ethernet port we've already mentioned. Pin headers on the board are said to provide access to two additional USB 1.1 host ports, AC '97 audio, two RS232 ports, one RS485 port, 12 GPIOs, IrDA infrared, and an eight-bit expansion interface.

Blue Chip says the RE1, which includes a four-wire touchscreen controller, has been designed for use with separately available personality modules (above) that connect it to a choice of three displays. Offered with or without touchscreens, the displays come in a 3.5-inch version with 320 x 240 pixel resolution, a 4.3-inch version with 480 x 272 resolution, and a 5.7-inch version with 320 x 240 resolution, according to the company.

Finally, the RE1 includes a real time clock with support for battery backup, and a watchdog timer, according to Blue Chip.

Further information

Blue Chip says that in addition to being offered with Windows CE, the RE1 will also be available with Linux. Pricing was not specified, but the device appears to be available now.
