4 line, 20 positions alphanumeric Standard LCD 2004A with HD44780 (or compatible) display controller and the standard 4/8 bit parallel interface. The optional available I2C interface fits right on the back of the display and turns its interface from parallel to simple 2-wire I2C (perfect for microcontrollers like Arduino to save on I/O ports).

Please click HERE to order the optional I2C interface module.

Standard LCD 2004A with 4 lines and 20 characters each comes with bright yellow LED backlight and high contrast. An I2C serial is available as option (SKU 26619). The display needs a 5V power supply for operation. With the I2C interface installed on the backside of the Standard LCD 20×4, the backlight can be controlled by software as well. Many different libraries for different programming languages and controller families are available, also countless examples.

    Larger display at 75 mm wide than the pixel-addressable displays, but only displays characters. Bright screen. I used the “I2C LCD Interface Module for Dot-Matrix Character Displays” to drive it through the I2C bus. Note that this display requires 5V to operate. I connected the interface to 5V and used a “Logic Level Converter 3.3V-5V Bi-Directional on-board 3.3V LDO” to connect to the 3.3V I2C bus of an ESP8266. The LCD2004 also has an unpopulated area of the circuit board where you can solder an ICL7660 chip plus a couple of capacitors; then the LCD2004 can operate directly with 3.3V. The level shifter is simpler.
