WEH001602A is a COB character OLED module with a PCB board, featuring a diagonal size of 2.29 inches and displaying 16 characters x 2 lines. This OLED shares the same outline size (80.0 x 36.0 mm), viewing area size (66.0 x 16.0 mm), and pinout as Winstar LCD item no. WH1602B. We recommend customers consider using this low-power 16x2 character OLED to replace existing STN character displays or for new projects.
This model offers various optional interfaces: default 6800, with additional options of 8080 and SPI. All Winstar standard COB OLED character types are equipped with an all-in-one Fonts controller IC. The built-in ROM standard font library includes ASCII, English, Russian, European, and Japanese character sets.
Operating at a logic supply voltage ranging from 4.8V to 5.3V (typically 5.0V), this OLED module has a wide operating temperature range from -40°C to +80°C, with storage temperatures from -40°C to +85°C. It boasts a high contrast ratio of 10,000:1.
