I'm attempting to build a user interface that provides minimal access to only a few crucial configuration options (network config, host name, reset defaults, etc). I have a SainSmart 20x4 LCD that I'm able to use with my pi, and the display size is really ideal for my purpose, but what I really need is something like a 20x4 version of AdaFruit's 16x2 LCD shield with keypad.
Has anyone come across something like this? If not, any suggestions on how to fabricate one without designing my own circuits/PCB?
Note that something along the lines of "combine [LCD product A] with [button product B] using 4 wires/solders" is more my skill level.
