Character UART 16x2 LCD Display Module

Model No. RC1602LR

RC1602LR 16x2 Character LCD display shares identical specifications with the RC1602E model. Both LCD display modules have the same dimensions, measuring 122 x 44 mm, Active area size is 94.2 x 20.0 mm, and built-in IC ST7066.The RC1602LR module features a default UART interface, with the option for SPI/I2C interface via jumper configuration. A noteworthy improvement in the RC1602LR 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), this module operating temperature range from -20 to +70℃. With a storage temperature spanning from -30 to +80 °C, it proves suitable for deployment in various environmental conditions.
