Arduiniq ver.3.0 (homemade compatible Arduino board)

   In case of dangerous experiments for an original Arduino board, like big consumption, high voltage at input module, etc I design and use more boards who use ATmega328P-PU microcontroller, but this is compatible with most official shields.
   Schematic is very simple, with few components:
   Board with components is:
   Schematic and boards are designed with Eagle PCB software and you can download sch and brd files for made boards by yourself. 
   A realistic 3D of my board is made with Eagle PCB software, too:
  
Note: ATmega328P-PU must have Arduino booloader on it...

   Schematic for conection between Arduiniq board and USB to TTL FTDI module is:
