 ===== Overview ===== ===== Overview =====
 +
 +This is a budget Arduino Mega R3 clone with a CH340G used as the USB-to-serial interface, rather than the ATmega16U2 used in the genuine Arduino Mega R3.  Based around the 16MHz ATmega2560, it is a functionally identical clone of the open source Arduino Mega.
 +
 +It can use most Uno shields, but some may require additional wiring or configuration adjustments due to differences in pin layouts and communication protocols. The Mega has fifty four digital I/O pins and sixteen analog inputs compared to the Uno's fourteen digital I/O pins and 6 analog inputs. It also has much larger memory - 256kB flash memory for the Mega compared to 32kB for the Uno. So in short, a mega version of the Uno.
