The SunFounder LCD2004 Module w/ 3.3V Backlight is a dot matrix module designed to display 20 characters including letters, numbers, and symbols. It supports 4-bit and 8-bit data transmission mode. It’s quite convenient for beginners to call the built-in library Liquid Crystal of Arduino IDE, no need to edit. The module has an adjustable contrast with a 50K potentiometer. To use the 3.3V backlight, just connect pin A to 3.3V, pin K to GND. The LCD2004 also works great with Arduino and other microcontrollers.

Work well

This is the second one of these that I've purchased. I was motivated by price for the first purchase; happy enough to buy it again. Note: you have to solder the header on yourself - for me this was an advantage since it let me use a 90º header instead of the supplied straight header.
