The Arduino Mega 2560 board.

The Arduino Mega 2560 is a microcontroller board that is often used in South Africa when you need lots of I/O pins and is based on the ATmega2560 chip. 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 an AC-to-DC adapter or battery to get started. The Arduino Mega 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila.

This board is a 100% identical clone and not the original Arduino Mega. We sold many of them and had no problems with these boards. they are high quality 100% identical to the original Arduino Mega but at a much better price.
