Arduino DUE & Bluetooth

Hi Anyone who will listen,

I am developing a robotic arm for my own personal use. I have a rare form of ALS. I'm loosing the function of my arms. I would like to control my arm using a Android Nexus 7 tablet. The arm have 7 servos. On a previous arm I am using the Arduino DUE. Can someone recommend a Bluetooth wireless modeule I should buy that is compatible with the Arduino DUE? Is t the 4.0 and can it fit right on to the DUE?

Thank you in advance
