Introduction

Arduino Mega Arduino is the high-end series of the Arduino controller. DFRduino Mega2560 is

based on ATmega2560 control chip as the core, with 54 digital I/O (input/output) ports (of which

14 can be used as PWM output), 16 analog input ports and 4 UART (hardware serial ports),

using a 16 MHz crystal oscillator.

Embedded bootloader enables the controller to download the program directly via USB without

any other external burning device.

Multiple ways of power supply can be free to choose, including the USB power supply and

universal power adapter and battery for external power supply.

Open-sourced software and hardware platform, large interacted community, easy development

environment and strong control ability, all together making the Arduino become the most

popular electronic product development tool currently.
