Finally I got my first test with Hatalógico and it looks promising: just out of the box PWM working. That means servos working right in the same platform as a powerful linux board! If you don't know the Hatalógico board for Raspberry Pi, go and check it here, there are 3 days left to get it at a special price and features.
