Stick Gets A New Bus

Gumstix has opened its architecture to a horde of daughtercards with the addition of a 96-pin system bus header on its Intel XScale PXA255-based connex 200g (200 MHz) and connex 400g (400 MHz) processor boards. These small (80 by 20 by 6.3 mm) boards hold 64 Mbytes of RAM and 4 Mbytes of flash containing Linux. There also is a USB client interface, three serial ports, and JTAG support. The connex 200g costs $109, and the 400g is $139. With prices starting at less than $20, daughtercards provide access to a range of interfaces like audio, Ethernet, 802.11b/g, Bluetooth, and USB.
