Intel's PXA255, the predecessor to the
PXA270 (Bulverde), was
announced in March of 2003. It has since been used in Windows CE-based PDAs such as the
HP iPAQ series, handheld computers such as Psion Teklogix's
model 7535, and even in a
jukebox. Processor modules based on the PXA255 have been marketed by
Strategic Test and
In-Hand, while Arcom
offers a PC/104 board based on the chip.
In addition to the PXA255 processor, CompuLab's ARMcore-GX is available with 16 to 64 MB of SDRAM, and between 1MB and 512MB of Flash. It also includes an LCD controller
verified with a number of LCD modules, CompuLab says, including some supporting resolutions up to 800 x 600 (SVGA).

- Power consumption under 1 watt
- PCMCIA controller
- GPIO lines
- Serial, LPT, PS/2 keyboard and mouse ports, IrDA
- Optional Ethernet, sound, touchscreen, hard disk, and USB ports
The module uses "CompuLab's aggregated module interface" (CAMI) to interface with carrier boards such as the PC/104-based
ARMbase shown below. Also, it is compatible with older ARMcore modules, CompuLab says.
