If you would like some input buttons for your evm you can solder some push buttons right onto the board.
Just connect them between the LEDs [REF CHECK WHICH SIDE OF LED!] and ground.
If you want to retain LED functionality, just send a command to turn off the LED prior to polling for the input status, otherwise you will read the output value rather than the switch!
