RC1604B Character LCD - Raystar

16x4 Character LCD Module

Model No. RC1604B

The RC1604B is a 16-character by 4-line monochrome LCD display module with dimensions of 70.0 x 60.0 mm. It features a default 68-series interface and a built-in ST7066U controller IC. The RC1604B operates on a default power supply of 5V, with an optional 3V version available. A negative voltage option is also offered for the 3V power supply. We provide various LED backlight options for the RC1604B, including yellow-green and white, or you may choose a module without a backlight.

The LED backlight can be powered via PIN1, PIN2, PIN15, PIN16, or pins A and K. The RC1604B module supports multiple font options, including English/Japanese and European character sets.
