Fox board!
Yesterday my fox board arrived! A complete linux system in just 66x72mm based on Axis Etrax 100LX with 32Mib RAM and 8Mib flash memory.
Features:
- Axis ETRAX 100LX 32 bit, RISC, 100MHz (100MIPS)
- 8MB FLASH 32MB RAM
- 1 Ethernet (10/100 Mb/s)
- 2 USB 1.1
- 1 serial console port
- 2 extension sockets with IDE, SCSI, serial lines, parallel ports, I/O lines, I2C bus interface
Yet I haven't tested the device perfomance comprehensively but I ran some (a bit dissapointing) network tests. I get aroung 150Kib / sec using secure copy which means I will have to wait for a stronger Fox to build my embedded torrent download server 
Acmesystems, the company which builds fox, besides the great name (see Acme Corp) is linux friendly and offers good (but not complete) documentation on various usage scenarios (e.g. lcd connections, wifi modules). The tools provided have some glitches as I haven't managed yet to recompile successfully the flash image using Axis SDK, even if I use the provided config file.
Anyway this board seems to be the best choise for starters on embedded systems considering both price and capabilities. If only Atmel's NGW100 had build in USB support...
