I finally got a chance to put together very first FAIO board and start writing the firmware for it to operate in Adaptive Switch mode.

In this mode the FAIO Switch will act as a basic switch interface with two 3.5mm Audio jacks that can be used to connect up to two Adaptive Switches and can be used to operate/navigate a smartphone or computer through switch control option in iOS or Android. An adaptive switch button can be connected to one of the 3.5mm Audio jacks to act as a selected switch button and another one to other 3.5mm Audio jack in order to move to the next item when it's setup as a switch.

I picked up an Adafruit Feather 32u4 Bluefruit LE board for this project.You will need to solder header pins to it before being able to use it.

Once the necessary components are soldered to the main board then you can go a head and stack the Adafruit Feather 32u4 Bluefruit LE board on the FAIO board.

The instruction manual will become available soon but until then you can see how it would lookalike.
