Description

WEH001601B is a COB structure 16×1 OLED (16 characters × 1 line) display module with a diagonal panel size of 2.25 inches. The module dimensions measure 80.0 × 36.0 mm, with an active area size of 56.95 × 5.55 mm. It integrates the WS0010-TX IC, supporting a default 6800 interface, along with additional options of 8080 and SPI, and operates with a 1/8 driving duty. All Winstar OLED Character COB modules are equipped with the all-in-one Fonts controller IC WS0010-TX, providing 4 font sets in one device. The built-in ROM standard font library includes ASCII, English, Russian, European, and Japanese character sets.

The logic supply voltage for WEH001601B is 5V (typical value), and the display current with a 50% check board is 30mA at 5VDD (typical value). This 16×1 OLED module is designed to operate in temperatures ranging from -40℃ to +80℃, with storage temperatures from -40℃ to +85℃. It features a high contrast ratio of 10,000:1.

The WEH001601B OLED series with a PCB board can easily connect to the application using wires. Customers do not need to develop additional PCB boards themselves. Four screw holes are designed on the PCB to facilitate easier installation of the module onto the application product.

This 2.25″ OLED module provides seamless integration into various applications, ensuring both functionality and ease of use.
