The WH1602S is a 16x2 monochrome character LCD display module with a COB (Chip-on-Board) structure, featuring the ST7066 controller IC (or equivalent). It supports multiple interface options, with the default being a 6800 4/8-bit parallel interface. For additional flexibility, users can select from SPI or I2C interfaces, supported by the RW1063 IC.
The module operates with a 5V power supply, with an optional 3V version available. When using 3V, the negative voltage is limited to 3V. The WH1602S is available with various backlight colors, including blue, green, white, yellow-green, amber, and red, all utilizing white LEDs for clear, bright display.
This module supports a range of character fonts and texts, including English/Japanese, English/West European, English/Scandinavian European, and English/Cyrillic (Russian). With a diagonal size of 1.88 inches, it operates within a temperature range of -20℃ to +70℃ and can be stored at temperatures between -30℃ and +80℃, making it ideal for both industrial and consumer applications.
