The Ultimate Arduino-Compatible Board for Android Accessory Development
Build powerful Android-connected devices with the Mega ADK (Blue) - a feature-rich development board based on the ATmega2560 with built-in USB host capability. Designed specifically for creating Android Open Accessory (AOA) projects, this board combines the expansive I/O of the Arduino Mega with seamless Android device communication. Available now from Tech Depot India, Bengaluru, with fast shipping and full technical support.
ATmega2560 Powerhouse
The ATmega2560 is one of the most capable 8-bit microcontrollers available for maker projects. With 256 KB of flash memory, 8 KB of SRAM, and 4 KB of EEPROM, you have ample room for complex sketches, large data tables, and persistent storage. The 16 MHz clock speed ensures responsive real-time performance for demanding applications.
Built-In USB Host via MAX3421E
The onboard MAX3421E USB host controller is what sets the Mega ADK apart from a standard Mega 2560. This chip allows the board to act as a USB host, enabling direct communication with Android smartphones and tablets using the Android Open Accessory protocol. No additional shields or breakout boards required - just plug in your Android device via the USB-A female port and start exchanging data.
54 Digital I/O Pins (15 PWM)
With 54 digital I/O pins, the Mega ADK gives you an enormous amount of connectivity. Fifteen of those pins support hardware PWM, making it easy to control servos, dim LEDs, drive motors, and generate analog-like signals. This pin count is ideal for projects that require controlling multiple sensors, actuators, and displays simultaneously.
16 Analog Inputs
Sixteen analog input channels with 10-bit ADC resolution let you read a wide variety of sensors - temperature, humidity, light, pressure, flex, force, gas, and more - all at the same time without multiplexing.
4 Hardware Serial Ports (UARTs)
Four independent hardware serial ports allow simultaneous communication with GPS modules, Bluetooth modules, GSM shields, other microcontrollers, or serial displays - without software serial overhead or conflicts.
Full Arduino IDE Compatibility
Program the Mega ADK using the familiar Arduino IDE. Select "Arduino Mega ADK" from the board menu, write your sketch in C/C++, and upload via the USB-B programming port. Access the full Arduino library ecosystem, including the USB Host Shield library for Android communication.
Tech Depot India Power Management
The recommended 7-12V input range (via the DC barrel jack or Vin pin) feeds an onboard voltage regulator that provides a stable 5V rail. The board also provides a 3.3V output for interfacing with lower-voltage peripherals. Reverse-polarity protection and a resettable fuse guard against common power mistakes.
What Makes the Mega ADK Special
Android Open Accessory Protocol
Google's AOA protocol allows external hardware to communicate with Android devices running Android 2.3.4 (API Level 10) or higher. The Mega ADK implements this protocol natively, meaning your board can:
- Send commands to an Android app - control UI elements, trigger notifications, or log data on a phone screen
- Receive data from an Android app - use touch inputs, accelerometer data, or GPS coordinates from the phone to control hardware
- Use the Android device as a display and interface - eliminate the need for expensive LCD screens or complex button interfaces
This opens up a world of possibilities where your phone becomes the brain, display, and cloud gateway for your hardware project.
