Arduino Mega 2560 Rev3 Development Board
HighCapacity 8Bit Microcontroller Board with 54 Pins
The Arduino Mega 2560 Rev3 is a flagship 8bit board powered by the ATmega2560 microcontroller. Designed for projects that require significant I/O capabilities and memory, it is the goto choice when the standard Uno's resources are insufficient. The board is compatible with most Arduino shields and can be programmed via the Arduino IDE.
54 Digital & 16 Analog Pins - Supports extensive peripheral connections
Massive 256KB Flash & 8KB SRAM - Handles complex code and large data sets
Supply voltage is recommended at 7-12V DC via the barrel jack, or 5V via USB
In the Arduino IDE, select the "Arduino Mega or Mega 2560" board from the Tools menu
Operating voltage is 5V. I/O pins are not 5V tolerant for 3.3V devices
