compatible with Google ADK Freaduino ADK / Android Open Accessory Development Kit

Freaduino ADK 100% compatible with Google ADK / Arduino Mage ADK

Freaduino ADK V1.0 demonstrate the use of Android Nexus S 2.3.4 Control RGB 3 LED's light off, the current version has risen to 2.0, the main difference is adjusted LAYOUT, board size and development of the official version v2.0 and exactly the same size, In addition Freaduino red color replaced.



Freaduino ADK V2.0 is Google ADK (Android Open Accessory Development Kit) 100% compatible upgrade. Google ADK firmware version in the Android 2.3.4 support only after a function, the purpose is to interact through the Android and Arduino, so enthusiasts have more games are played. For example, using the Android UI interface control production, and peripheral drivers do the Arduino to control, such as sensors, motors, joystick, LCD display, and so on. The Freaduino Mage2560 completely 100% support and Google ADK interaction. Freaduino addition to the more than excellent Layout layout, but also more convenient in use.For example: Add the 3.3V and 5V power supply switching options, so you can use more support and direct such XBee, Bluetooth Bee, RF, and the like need to 3.3V operating mode of the module. For example, the Reset Button and then into the side of the button, so use the Shield will not appear when the expansion board can not be the case according to the Reset button.

These are Freaduino exquisite small intimate details of the design, more user-friendly design, we want users to use the process to appreciate our focus.

Arduino Mage ADK's Freaduino ADK what is the difference?

1 Operating voltage 3.3V / 5V optional. Arduino Mage ADK can only work in 5V, 3.3V all levels often encountered in the interface module, IO ports can not be directly connected to the conversion level needs to be done - such as SD Card, Bluetooth module. Iteaduino toggle switch so that it can work at 3.3V, this time the IO port voltage is 3.3V and 3.3V can work with the module level. (Note: 3.3V 16M state of the MCU clock is overclocking, but after the actual test, MCU job stability, ease of use)

2 more power. Arduino using FT232RL 3.3V output supply, the maximum output current of less than 100mA, encountered peripheral modules require high current, it will have enough power. Freaduino use 1117-3.3 output 3.3V power supply, the maximum current of 800mA. Arduino's 5V supply only 500mA, LDO and Freaduino change the original design DCDC, can provide up to 2A of 5V power supply.

3 more visible LED. When the lights Arduino board expansion will be blocked plug, can not see the PWR, TX and RX indicators. Freaduino the edge of the light moved to the board, even if there are expansion boards can also see the light.

4 is easier to press the reset button. Arduino reset button in the expansion board inserted will be blocked and can not be reset on the motherboard. Freaduino reset button to move the edge of the board, can easily click to whenever.

5 Wide input voltage. Arduino supports only 7-12V input, but Freaduino support 7-23V input.
