Hi there, today I have finished to make a schematic for a board I want to build, just to acquire more practice in this area.
I built an mp3 player with an Arduino Fio and the Sparkfun mp3 shield. Now, starting from the schematic of these boards, I have made a new scheme who has both the mp3 and the Arduino microcontrollers (on the same board), removing some resistors and capacitors (I believe I don’t need).
These are the schematic of the two boards (Arduino Fio and mp3 shield):
And I have attached the schematic of the board I want to made.
If you need some additional information, ask me. I don’t know if this is a simple check, but I say thanks in advance to the people who want to answer.
