"Freeduino-Mega2560 ADK Board" is  ATmega2560 based Arduino Mega compatible board USB Host Interface.

This is the First Arduino Mega compatible ADK board made by Indian Manufacturer. 

This board allows you to control hardware circuits (interface circuits) from Android Powered Devices like Android Phone. Refer  to System requirements from this product's user manual for Android support etc.

Freeduino-Mega2560 ADK Board  has Port I/Os as mentioned below:

• 54 Digital input/output pins (of which 14 can be used as PWM outputs)
• 16 Analog inputs (These Analog lines can be used as Digital I/O if ADC is not enabled from the Arduino program code)
• 4 UARTs (TTL Serial, Not RS232 level)

Read User Manual which has extensive details about the Installations and usage procedure.

Downloads: ( Before downloading and using these projects, prepare your system as explained in the User Manual.)

1. Android App Project based on MicroBridge

2. Arduino Sktech based on MicroBridge

USB Host Interface:

Apart from plain Arduino based on ATmega2560, board has USB Host interface designed around MAX3421E
This allows the Arduino compatible board to act as USB Host.

What is ADK?:
The Android Open Accessory Development Kit (ADK), is part of latest Android 3.1 platform and also back ported to Android 2.3.4
ADK allows Android Phone to act as USB Device where as the “Freeduino-Mega2560 ADK” will act as USB Host. This allows communication between Android Powered Devices (like phones) and external Hardware like industrial controls.

What is MicroBridge?:
MicroBridge is an Android Debug Bridge (ADB) implementation for microcontrollers.
MicroBridge allows stock, unrooted Android devices to talk directly to USB host enabled microcontrollers, thus enabling phones to interface with servos, drive DC motors, talk to I2C and SPI devices, read ADCs, and so forth. MicroBridge works on Android 1.5 and upwards.

Notes:

The MAX3421E communicate with Arduino with the SPI bus. It uses Pins Digital: 7 (RST), 50 (MISO), 51 (MOSI), 52 (SCK). Thus do not use Digital pin 7 as input or output because is used in the comunication with MAX3421E.

Do not plug both power sources at same time

While using this product, there are possibilities of software and / or hardware damage / malfunctioning / crashing of the Mobile Phone / Tabs / Devices connected to it. In such event user of this product will be solely responsible the same. Embedded Market, it’s staff or the distributor cannot be held responsible for damages in any form including but not limited to digital data loss, loss of hardware, loss of time etc.
