95% of 16x2 and 20x4 character displays have a standard controller (HD44780) with a standard pinout. They are available in many colors. This module lets you add these displays to a mainboard. Soldering is needed to add a display. Please note that the contrast pin is fixed to GND through a 0ohm resistor. 90% of displays we tested work fine at max contrast. If contrast is too high, the resistors can be physically changed. Please see schematics under downloads.

Tip: In software, use the Character Display Module drivers.
