Compatible Arduino Mega2560 is fully compatible with Genuine Arduino Mega 2560 and makes no difference, only the manufacturer changes. 

The MEGA 2560 is designed for more complex projects. With 54 digital I/O pins, 16 analog inputs and a larger space for your sketch it is the recommended board for 3D printers and robotics projects. This gives your projects plenty of room and opportunities.

The Compatible Mega2560 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 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila.

The Mega 2560 board can be programmed with the Arduino Software (IDE). For details, see the reference and tutorials.

The ATmega2560 on the Mega 2560 comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol (reference, C header files).

NOTES

• This is a 100% compatible board similar to the Arduino Mega 2560.
• The package includes only the standard Mega2560 board, you can find in our catalog USB cable, 12V power supply and everything else you need for your construction.
