If you like the speed and simplicity of ARM Cortex M0+ chips, but want to just dip a toe in, you'll fall in love with the adorable little LPC810. This particular chip in DIP8 really jumped out at us since it's so different than what people usually think of when they hear 'ARM'. The DIP8 LPC810 is still somewhat of a challenge to use precisely because it's so small (by ARM standards, anyway): 4KB flash and 1KB SRAM. But the low price, 32-bit processor, 12MHz internal oscillator, I2C/SPI/UART with configurable pin-matrix, and built-in serial bootloader is quite nice.
