The WINSTAR WH1602A is a dot matrix LCD display module capable of displaying 16 characters by 2 lines, featuring a Chip on Board (COB) design and a 2.26-inch diagonal screen size. It is equipped with the ST7066 controller IC by default, which supports the 6800 4/8-bit parallel interface. Optional interfaces such as SPI and I2C are available using the RW1063 controller IC.
This dot matrix LCD display supports a standard 5V operating voltage, with an optional 3V supply (note: when operating at 3V, the negative voltage supply is limited to 3V). The LED backlight can be driven via PIN1, PIN2, PIN15, PIN16, or terminals A and K. WH1602A offers multiple backlight color options, including blue, green, white, yellow-green, amber, red, and white LEDs.
The ST7066 controller IC offers multiple character font ROM versions for customers to choose from, including English/Japanese, Western European, Eastern European, Scandinavian European, Cyrillic (Russian), and Hebrew/Arabic.
The WH1602A series includes several interface variants:
► WH1602A: 6800 interface (ST7066 IC)
► WH1602A2: SPI interface (RW1063 IC)
► WH1602A3: I2C interface (RW1063 IC)
This LCD 16x2 1602A dot matrix LCD display module is ideal for applications requiring clear alphanumeric display and flexible interface options. For detailed specifications, please refer to the LCD 1602A datasheet.
