Arduino Mega ADK - R3
The Arduino Mega ADK R3 is a microcontroller board based on the ATmega2560, designed specifically for developing accessories for Android devices. It features a USB host interface that allows it to connect with Android-powered phones and tablets using the Android Open Accessory (AOA) protocol.
Based on the Mega 2560, the ADK shares the same powerful specs — 54 digital I/O pins, 16 analog inputs, 4 hardware serial ports — while adding USB host capability for Android accessory development. Compatible with Android 2.3.4 and above.
Key Features
- USB Host Interface – Connect with Android devices using the Accessory Development Kit protocol
