It’s a significant update. The Arduino UNO and Arduino Mega 2560 update the Duemilanove and Mega respectively. They now use an ATMega8U2 instead of an FTDI USB to serial converter chip.

Apparently, so does [salmec] who developed the Mowerino around an Arduino Mega 2560 board. As you might expect, the robot uses sharp blades so, you probably want to be careful.

Meanwhile, the Arduino Mega is getting the same USB chip along with an ATMega2560 processor with twice the memory. Right now only 128K is available, but that's a software limitation and they're ...

This paper reveals the easy way to control a simple frequency driver, in this case, the Arduino Mega 2560 board acts as a driver controller, driving a BLDC motor also known as the electronically ...
