Help me by sharing this post

Thesem is the schematic for the Arduino based smartwatch that uses the ATmega328 chip in a QFN format. It might be a bit tricky to solder but using solder paste and hot air should go nice... Have this schematic in front of you while soldering in order to know all the values for resistors adn capacitors.
