This is a basic 16 character by 2 line alphanumeric display with white text on a blue background. It uses an HD44780-equivalent controller with a 5 x 7 dot matrix character plus cursor, and it has an LED backlight.
It works with almost any microcontroller, since the HD44780 interface code is freely available and well documented.
The display can run in 4-bit or 8-bit mode and needs a minimum of six I/O pins in 4-bit mode. Typical connections are power, ground, a contrast potentiometer, the register-select (RS) and enable (E) lines and four data lines. The Arduino LiquidCrystal library supports it directly.
The display has bare pins, so you will need a pin header, jumper wires and a contrast potentiometer, or an I2C adapter if you want to save pins. Adjust the contrast until the characters are clear, and limit the backlight current with a resistor if your module has no built-in one.
Students, hobbyists and product designers who need a cheap text display for timers, meters and menus.
Connect power and ground, add a 10 kilo-ohm potentiometer between power and ground with its wiper on the contrast pin and connect the backlight pins through a resistor if the module does not have one. Then wire RS, E and four data lines to the Arduino and use the LiquidCrystal example. If you see two rows of blocks, the contrast is set too high.
Sixteen characters on two lines.
An HD44780-equivalent.
At least six, in 4-bit mode.
Blue, with white text.
Yes, with the standard LiquidCrystal library.
