RC2004A1 Character LCD - Raystar

20 Characters × 4 Lines Monochrome Display Module

Model No. RC2004A1

RC2004A1 20 Characters × 4 Lines monocharome LCD display has the same specs as RC2004A. The only difference between them is the position of pins. RC2004A has 16pins on the PCB; pins of RC2004A1 are on the FFC connector. The RC2004A1 default interface is 6800 with built-in IC ST7066; if you require interface such as SPI or I2C, they’re also available, but the IC will be replaced with RW1063. Default power supply of RC2004A1 module is 5V (3V is optional). Negative voltage is an available option for 3V module.

Raystar provides various LED backlight combinations for RC2004A1 module, such as yellow-green and white. You can choose module with LED backlight or without it. There are many LCD modes to choose from, for instance, STN negative blue, STN positive yellow/green. RC2004A1 offers a selection of fonts, including English/Japanese and European.
