PCBs and breakout boards, designed by the MobiFlight community

The board uses XH JST connectors for the individual buttons and for connecting to the Prototyping Board. Four 8 bit input shift register are daisy chained. Each input has a LED beside the connector which indicates if the button is pressed.

For more information on how to configure the board with MobiFlight, check out the MobiFlight Connector documentation.
