This site has been great fun, but it has run its course, and it is time to move on. Please get what you want from the site before January 1, 2020. Some pages will move to another site but most will go away.
The Diavolino is a Arduino Pro-like board, in that it is stripped completely down to the lowest possible parts count. There isn't even a power supply connector! This thing is intended to be the bare minimum. It also is about the craziest looking Arduino clone out there. The standard 6 and 8-pin connectors are an extra cost option.
With no voltage regulator included (there is a place for a TO-92 size regulator) you will need to supply the correct voltage to the board. That voltage is the determining factor for the MCU's maximum frequency. It needs to be 4.5 to 5.5VDC for the supplied 16MHz crystal. Here is a ATmega328 clock frequency calculator to help decide the voltage and frequency.
