Our very own version of the popular Arduino Mega development board (HCARDU0092). It hast been designed from the open source revision 3 Arduino Mega reference design and comes pre-flashed with the Arduino bootloader. This board is 100% compatible with all shields and modules compatible with the Arduno Mega. It is an ideal alternative if you are looking for a standard Arduino board but with significantly more Memory and IO compared to most other Arduino development boards. Its very low price together with the freely available Arduino development environment provides a cheap and easy way to get started.
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analogue 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 Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila. The Mega 2560 is an update to the Arduino Mega, which it replaces.
Revision 3 of the board has the following new features:
-- 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near the RESET pin, the IOREF that allows the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that uses the AVR, which operates with 5V and with the Arduino Due that operates with 3.3V. The second one is not a connected pin, that is reserved for future purposes.
-- Stronger RESET circuit.
-- Atmega 16U2 replace the 8U2.
