The WH1602B series is one of WINSTAR's most popular LCD display modules in 16x2 format, designed to meet a wide range of system integration needs. Each module features a 16-character × 2-line display format, supports either 5V or 3V power supply, and is equipped with a standard controller IC—ST7066 or RW1063, depending on the interface type. These modules include 8-character CGRAM for user-defined characters and offer optional access to low-level commands for advanced control.
Unlike many standard COB character modules that require an external control board for serial communication, WINSTAR’s WH1602B1 (SPI) and WH1602B3 (I2C) integrate the interface controller directly on the COB. This makes the character display LCD 1602 module easier to implement while reducing component count and simplifying PCB layout. With only two I/O pins, users can achieve flexible control using either hardware or software methods.
This series supports multiple interface options—including Parallel, SPI, and I2C—to meet diverse application requirements. If your design requires a 6800 parallel interface, select model WH1602B. For systems that require Traditional or Simplified Chinese font support, we recommend our graphic LCD module WG14432B.
