WINSTAR WH1602M is a 16x2 character dot matrix LCD display module built with ST7066 controller IC or its equivalent. It supports a default 6800 4/8-bit parallel interface and is also available in SPI and I2C interfaces using the RW1063 controller IC. The module operates on a default 5V supply (3V optional), and when operating at 3V, the negative voltage supply must also be 3V.
WH1602M supports various backlight colors including yellow-green, blue, green, white, amber, and red. The LED backlight can be driven through pin 1, pin 2, pin 15, pin 16, or A/K pins. The built-in ST7066 IC offers multiple font options, including English/Japanese, Western European, Eastern European, Scandinavian European, Cyrillic (Russian), and Hebrew/Arabic.
The WH1602M series offers different interface versions, as listed below:
► WH1602M : 6800 interface (ST7066 IC)
► WH1602M1 : SPI interface (RW1063 IC)
► WH1602M2 : I2C interface (RW1063 IC)
