The relationship Between 3 Practical Controller Board
The final time, we have now an excellent expertise of Arduino Duemilanove, then do you understand Arduino mega 2560? What's the partnership in between them?
Arduino mega 2560, which can be compatible with most shields designs for the Arduino Duemilanove. It's considerably related advantage with Duemilanovo.
1, The two of them really are a microcontroller board based upon ATmega, the main difference is Arduino Duemilanove determined by the ATmega168 or ATmega328 and mega 2560 according to the ATmega2560.
2, the two of them are basically connect it to a computer by using a USB cable or energy it with an AC-to-DC adapter or battery to obtain started out.
Arduino Mega 2560 Sample debugging
When working with it, the initial stage is doing sample debugging. With Arduino UNO R3 , a more important change of mega 2560 would be to change serial USB aspect with ATmega8U2 single-chip microcomputer to know.
So as to distinguish the three controller boards, hope this table can help you!
