Raystar Launches RC1602B LCD Modules for Diverse Displays
March 7, 2026
The RC1602B series features a 2.26-inch 16x2 character LCD display module. Maintaining identical specifications to the RC1602B1 model, both variants share compact dimensions of 80.0 × 36.0 mm and incorporate the widely-used ST7066 controller IC. This design ensures effortless replacement and smooth integration across different application scenarios.
For traditional applications, the series defaults to a 6800 parallel interface. To accommodate modern control requirements, users can opt for SPI or I2C interfaces by replacing the IC with RW1063. This adaptable interface selection enables straightforward connectivity with various microcontrollers and embedded systems, significantly expanding its potential applications.
The series offers multiple LED backlight color options including vibrant yellow-green, crisp blue, pure white, warm amber, and bright red. These diverse choices allow users to select optimal display characteristics based on specific application requirements or aesthetic preferences, enhancing both functionality and visual appeal.
For power-sensitive implementations, the series provides a backlight-free version. In low-power mode, these modules substantially reduce energy consumption and extend device operational life, making them particularly suitable for battery-powered portable devices and IoT applications.
The modules support standard 5V power supply while offering 3V alternatives. Certain 3V versions can incorporate negative voltage options to optimize display performance. This flexible power architecture ensures compatibility with various electrical environments, increasing overall versatility.
The primary distinction between RC1602B and RC1602B1 lies in pin placement—the former features top-mounted pins while the latter utilizes bottom-mounted configuration. This design differentiation provides additional installation flexibility to accommodate different PCB layouts and device structures.
Backlight compatibility is maintained through multiple drive options including PIN1, PIN2, PIN15, PIN16, as well as A and K connections. This multi-faceted approach simplifies integration with standard 16-character x 2-line LCD configurations without requiring complex circuit modifications.
