Sometimes it's necessary to connect external buttons to your application, for example if you build a device that has some buttons on the front of the case.
This module allows you to connect up to 7 external buttons. And additionally it has 7 'debug' buttons rigth onto it! That is very useful if you are in a very early stage of development. In that case, you can test your application with the onboard buttons, and once you are finished, you just connect the final buttons.
Every Button press/release fires an event. So it's very easy to
handle button state changes!
Of course a driver is available. Please contact me!
