Character Display LCD 20x4 - RC2004D

Character Display LCD 20x4

Model No. RC2004D

RC2004D is a monochrome 20x4 character LCD display module. Module size is 87.0 x 58.0 mm. The series has built in IC RW1063, supporting default interface 6800; other available options for interface are SPI and I2C. Default voltage is 5V; when using 3V, the supply for negative voltage has to be 3V also.

RC2004D: supporting 6800 interface
RC2004D1: supporting SPI interface
RC2004D2: supporting I2C interface

RC2004D offers multiple combinations of LED backlight, LCD types, different kinds of polarizer and fonts for you to choose from. Feel free to contact us for more details.
