DIY Drones has been working with Google on an Android-compatible RC interface board. They call it the “PhoneDrone board for Android”, and it’s a way to connect any Android device (2.3.4 or higher) to the world of RC and UAS.
The board has 8 channels of RC in and out, with PWM-to-PPM conversion and multiplexing between RC and Android control. Plugging the Android’s phone USB connector into the board gives two-way communications with RC gear and any other board, such as APM.

Does anybody know where I can get one of these? It appears that DIY Drones is sold out still…
