Nano DIP: the smallest complete Arduino board 33 x 10mm

Arduino Nano DIP board

The Arduino-compatible Nano DIP is similar to other Nano boards but it uses the new generation ATtiny3217 processor instead of the older ATmega328P.
It maintains compatibility with the Arduino Nano while offering additional features.
Moreover, it is the smallest complete Arduino compatible board ever made, measuring just 33 x 10 mm - the same size as an ATmega328P chip.
