Cheapest micro running linux?

Started by Andreas December 1, 2004
Hi,
I ask me what is the cheapest micro capable of running (�C)Linux. I know 
many ARMs, H8, Motorola Coldfire... Is there anything else? What derivat 
is suggested? No special needs for power consumption, clock/MIPS, 
integrated peripherials.

Thanks!

Is this strictly for a technology demonstration? The limiting factor tends to be memory. A cheap micro will require off-chip RAM and flash. A more expensive micro will require only one of those off-chip devices. Lowest overall system cost, probably I would say you're looking at ~$10 for the micro and $3 for RAM (in small quantities), for a low-end ARM7 and say 16Mb RAM.

For ARM, the cheapest alternative from Atmel is the AT91M40800 + Add Flash + PSRAM -- Best Regards Ulf at atmel dot com These comments are intended to be my own opinion and they may, or may not be shared by my employer, Atmel Sweden.

Perhaps a VIA board with a 386 complatible ? For one-of, with the leats work, with plenty of peripherals and everything. from 69$US As far as I know, VIA is the successor of Cyrix. We onve measured 8Watt for Linux including a 3.5" harddrive. Rene --=20 Ing.Buero R.Tschaggelar - http://www.ibrtses.com & commercial newsgroups - http://www.talkto.net

$51 per 1000, with Linux already configured.

Maybe a linksys WRT54G Wireless router.

200-Mhz MIPS-CPU ,  4M-Flash , 16M-Ram , 5 x ethernet ports , 
1 x 54Mb Wi-Fi , allready runs uC-linux , and Linksys GPL'ed the code,
as required , and even included a full MIPS Linux Toolchain(binary) in
the Sourcepackage.

If you add a MAX233 , to the board (solder pads are there) , then you
get 2 x Rs232.

The WRT54GS , has double Ram+Flash , but costs a little more.

Think WRT54G  around $70

Well the cheapest ARM based board that you can put uClinux on are:
Dlink DI614+ Rev A. About ~$US20 off of ebay, Compaq CP-2E/2W ~$US15 off of
ebay, and other (i.e. WAP11, AP9000, CompUSA 4 port router (FMI)). Some 
soldering required.
