Introduction The Dreamer Nano V4 is a surface mount breadboard embedded version of the ATMEGA 32U4 with integrated Micro USB. It has everything that Arduino Leonardo has (electrically). Physically, it is just missing power jack to save space. Using the ATmega32U4 as its sole microcontroller allows it to be cheaper and simpler.
