MEGA ADK R3 for Arduino Development Board Controller Mega2560 Mainboard New

About this deal

The MEGA ADK R3 is a microcontroller board based on the ATmega2560 that adds a USB host interface for connecting to Android-based phones, along with a power supply boost converter to charge the phone from DC power while it is plugged in. The R3 revision brings pin-compatibility with the Mega R3, introducing an IOREF pin and duplicated SCL/SDA pins next to the AREF pin. It runs at 5V working voltage, accepts 7-12V input, and packs 256 KB of flash, 8 KB of SRAM, and 4 KB of EEPROM. The board is compatible with Android's Accessory Development Kit examples and offers 54 digital I/O pins, 16 analog inputs, 4 hardware UARTs, and a 16 MHz crystal oscillator. The onboard bootloader means you can upload sketches directly over USB without an external programmer, and the board can be powered via USB or an AC-to-DC adapter or battery. It is also compatible with most shields designed for the Arduino Uno , making it a versatile choice for hobbyists and developers working on projects that involve Android device integration, robotics, or any application requiring extensive I/O.
