Arduino Mega 2560 ATmega2560-16AU w/ Cable & Case

Description

The Mega 2560 ATmega2560-16AU is a powerful microcontroller board designed for advanced embedded projects, offering significantly more I/O and memory compared to standard Arduino Uno boards. Built around the ATmega2560, it features 54 digital input/output pins, 14 of which support PWM output, alongside 16 analog inputs and 4 dedicated hardware UARTs for robust serial communication. This board is an ideal choice for applications requiring numerous sensors, actuators, and complex control logic.

A notable feature of this Mega 2560 variant is its integrated USB host interface, based on the MAX3421E IC, enabling direct connection and interaction with Android-based phones, keyboards, mice, and various game controllers. Powering the board is flexible, allowing supply via the USB connection, an external DC adapter (7-12V recommended), or the VIN pin, with automatic power source selection. The ATmega2560 comes pre-programmed with a bootloader, simplifying code uploads via USB using the Arduino IDE without needing an external programmer.

This board enhances compatibility with Revision 3 (R3) features, including dedicated SDA/SCL pins near AREF and an IOREF pin for shield voltage adaptation, ensuring forward compatibility with 3.3V Arduino boards like the Due. It also incorporates a stronger RESET circuit and USB over-current protection for enhanced reliability. The included transparent acrylic case offers basic protection for the board, while the USB cable ensures immediate connectivity out of the box.
