The Romi 32U4 Control Board has a set of through-holes in the center where a 2×7 header can be soldered to connect an 8×2 character LCD {{polpl|356}} (or any other LCD with the common [https://www.pololu.com/file/0J71/DMC50448N-AAE-AD.pdf HD44780 parallel interface] (109k pdf)). You can adjust the LCD contrast with the potentiometer on the top right of the LCD connector. We recommend using a 2 mm slotted screwdriver to adjust the contrast.

The Romi32U4 library provides functions to display data on a connected LCD. It is designed to gracefully handle alternate use of the LCD data lines by only changing pin states when needed for an LCD command, after which it will restore them to their previous states. This allows the LCD data lines to be used for other functions (such as pushbutton inputs and LED drivers).
