An Arduino is a little more complicated than a breakout for the ATmega. There's a power regulator so you can use any 6-12V supply, a USB to serial converter chip (FT232R), and various passive components to support the chip.
The LPC810 is neat, but very limited in flash memory and I/O. Check out the NXP LPC1114FN28--it's a 28 pin breadboard friendly DIP package ARM cortex M0: http://www.nxp.com/products/microcontrollers/cortex_m0_m0/lp... 32k of flash and a similar amount of I/O as the ATmega328P used in an Arduino. The big advantage of ARM is that you can use free in circuit debugging tools like OpenOCD to debug and step through code in real time on the chip. It's not easy to do that on an Arduino without a $50+ adapter.
