Character LCD UART Display Module 20x2

Model No. RC2002AR

RC2002AR 20x2 Character LCD display shares identical specifications with the RC2002A model. Both LCD display modules have the same dimensions, measuring 116 x 37 mm, Active area size is 73.5 x 11.5 mm, and built-in IC ST7066.

The RC2002AR module features a default UART interface, with the option for SPI/I2C interface via jumper configuration. A noteworthy improvement in the RC2002AR series is the introduction of a new instruction set, eliminating the necessity to understand the ST7066 LCD Controller commands. The display setup is simplified with the built-in MCU and instruction set, enabling users to concentrate solely on application layer programming. Furthermore, users can effortlessly fine-tune backlight brightness and LCD contrast using commands provided in the instruction set.

With a logic supply voltage range of 4.5V to 5.5V (typical value at 5V), the module work within temperature from -20℃ to +70℃, storage temperature covers from -30℃ to +80℃, it proves suitable for deployment in various environmental conditions.

This RC2002AR display LCD 20x2 offers a selection of fonts, including English/Japanese, Europe and Cyrillic (Russian), etc. Feel free to contact us if you need full datasheet or more info of this display.
