What boards and modules work with Android?


I am looking for a minimal hardware setup for my project. Up to now I used the ADK Mega with a Samsung Galaxy S3. The communicated succesfully via USB. The new board:

  • should not have an usb host shield,
  • should have a Bluetooth shield to communicate with the device,
  • should have a battery/li]

Do you have any suggestions what I can use? I am looking forward to user the Arduino Mini or Arduino Nano. How can I see what modules work with this? and when they are compatible? Do you have any recommendations for tiny bluetooth boards and batterys working with the boards?

Thanks, best regards filyra
