Linuxstamp

Description

The Linuxstamp is designed to be a general purpose processor module. It is designed to work as a stand alone module (SD card, ethernet and USB/Serial converter are all on the module). This allows all initial development to be done without a motherboard, but for integration into a specific project a motherboard with specific features could be designed.

Features

• Atmel AT91RM9200 processor (Arm9 processor with MMU)
• 32Mb SDRAM (Only limited by 1x 54-TSOP SDRAM chip)
• 8Mb SPI Dataflash
• 1x 10/100 Ethernet
• 1x USB host port
• 1x SD card slot
• Serial debug port access through FTDI USB/Serial converter
• JTAG port
• 2-Layer PCB design

Booting

The AT91RM9200 has several features the faciliate easy booting. There is a good description of the booting order here. The AT91RM9200 will look at the dataflash for an initial program to execute. Atmel provides a tiny program that lives in the Dataflash and loads u-boot.

Pricing

The parts cost for qty 1 is $75 from digikey, and $55 for qty 100
I'm sure this can be greatly reduced with higher quantity
We will make a small run soon, and I will let you know when these are available

Discussion

Can I plug a USB peripheral into the Linuxstamp, such as a USB Wifi adapter? --DavidCary 22:02, 17 April 2007 (PDT)
Yes, any USB device that is supported by the kernel should work with the Linuxstamp. --Linuxvolts 23:15, 18 April 2007 (PDT)
