Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

I hope you will not be selling these?
One day I think I'll design a through-hole version of the axon for people without any money like me.(Some parts will have to be approximated of course)

Today I will post both Eagle's files and electronic parts list you need to create your own homemade axon clone.total cost is estimated ~ 30euro for EU or $ 40 for U.S.estimated time working for the finished product is ~ 4 hours of work.
the USB to UART chip, regulator and crystal are easily another 20-30euro.
IMO best way would be use Futurlec part # 100PINTQFP, solder on a 640/2650 and you have all header pins broken out, crystal, voltage regulator, etc and you are done.
Also the mega32 is not the "biggest", it is outdated, the mega644 is currently the biggest (more features than mega32)
EDIT:Mega640 $11.8 from digikey and basic axon parts list from futurlec below. Few things like a resistor array or two are missing but nothing more than $5-$10 at most.Sure, not a fancy pcb but who cares? This is for thru-hole components.So, like ~$25 for a board! If i have left anything out, please tell me.
Good luck with the soldering! I mean, how many of you can even see the 28 pins on the CP2102?
Plus, don't forget that rapid personalized tech support and a pre-loaded bootloader comes with the Axon price.
