This module contains 4 74HC165D PISO shift registers with pullup resistors on all 32 inputs to directly connect individual buttons to it.
The pins can be read by the Open FFBoard or any Arduino via SPI. Multiple modules can be chained to get even more inputs. Output is disabled with CS low (Can be modified to active LOW CS using smd jumpers). The CS pin latches the inputs and has to be high while shifting.
