I'm looking for some options to extend the PCA10028 with a keybord and a numpad. This would give great options to play around with passkey topics.
As the PCA10028 supports the Arduino pinout i guess that Arduino LCD/Keypads would be an option. But i didn't find a board that has keypad with buttons from 0 - 9 and an LCD.
Is there a recommended board? Has Nordic planed support for one of these boards?
