Tue Jan 12 10:05:34 CET 2010
The Calao USB-A9260 and USB-9G20 boards are manufactured and sold by Calao Systems
<http://www.calao-systems.com>. They are built around an AT91SAM9260 ARM SoC
running at 180MHz and an AT91SAM9G20 ARM SoC running at 400MHz respectively.
They feature an Ethernet port, 64Mo of SDRAM, 256Mo of NAND flash, two USB host ports,
and an USB device port. They also feature a FTDI2232 converter which provides the ability
to use the DBGU serial port & the JTAG port over a USB interface.
