The Mega 2560 is a microcontroller board based on the atmega2560. It has 54 digital input/output pins (of which 15 can be used as pwm outputs), 16 analog inputs, 4 uarts (hardware serial ports), a 16 mhz crystal oscillator, a usb connection, a power jack, an icsp header, and a reset button. It contains everything needed to support the microcontroller, simply connect it to a computer with a usb cable or power it with a ac-to-dc adapter or battery to get started. The mega is compatible with most shields designed for the duemilanove or diecimila. The Board is a microcontroller development board based on the ATmega2560. Thanks to the bootloader, it is possible to download programs directly via USB without going through other external writers. The power supply can be powered by USB directly or by using an AC-to-DC adapter and battery as an external power supply.
Based on the open source code principle, you can download and use it for free in topic production, school teaching, motor control, interactive works, and so on.
