3 Button Controller & IC

The Expat Audio 3 button control board is a relatively simple board, designed to drive 3.3V CMOS logic outputs based on 3 momentary push switches. Switches for your design no longer have to be ugly toggle switches, they can be sexy looking backlit switches, that in turn toggle relays on and off deeper inside your product. 
Typical uses for this board are either for Mic Pre Frontend boards,or for use in a monitoring controller.

An user manual for the board can be found HERE 

What's in the box?
Bare PCB with a pre-programmed Microcontroller
What else do I need to buy?
Switches, power supply IC and passives - list below from Mouser.

The board ships with a pre-programmed IC that converts momentary button presses into latching buttons, but not exclusive (i.e. you can switch more than one item on at a time). Alternative code is available to do exclusive on/off. Contact us for details!
Switches are available separately.
