I wish there were some improvements in the I/O aspect of the board. Having tried to use an RPi for a small automation project, I felt limited by the single ADC input and single PWM output. I was faced with using an Arduino daughter board to do the actual IO or going with a BeagleBoard.

Driving an arduino from a pi is still the way to go, which is a shame. I’d have liked to have seen more PWM too.

  Look at pca9685-based i2c pwm driver boards, it gives you 16 channels and is much more stable and easier to control from userland code than RPi gpios.
