that's the ATmega328p 28pin DIP
no postage on RS for sure
I think there's no postage on Farnell either
the only way I can tell is after they get my credit card!
you'll still need the BootLoader though as raw chips come without
You just need an AVR programmer, which are about £10-15 and you can bootload chips from the Arduino software.

why would we want photos in a photo forum!?!?!
crikey you have been a busy chap
also pleased to see your breadboards are as "well structured" as mine!
can't wait to see the final PCB and product
is that an upside down Arduino mega in the pictures?
hard to tell when it's being so coy!
The mobile version is using the 328p simply because it contains more than enough IO pins and because once built and tested there will be no need to re-program it so the chip can go on the board and it is quite simple.
If the larger version is using the Mega purely because of the number of I/O pins, you're really best off just using a 328P with Multiplexers, it'll be a LOT cheaper. 2-3 quid for a 328P, and 50p each for multiplexers is a lot cheaper than 50 quid for a mega.
Ok, even if you can get the Mega for less than £50 (most places have it for £40-45), it's still a lot cheaper to integrate the uC into your own device than it is to actually put an Arduino Mega in there.
Most people aren't going to care about updating their own firmware as long as it works (those that do, are probably capable of building their own anyway), so having a Max232, USB socket & USB cable aren't really all that essential.
care to share where you can get mega so cheaply?
I can't even find kits anywhere:bang:
