The WEA012864A is an extension of the WEO012864A OLED display module, featuring an integrated PCB board that enhances its usability and versatility. With a diagonal size of 1.54 inches and a resolution of 128x64 pixels, this module is designed to deliver clear and detailed graphics, making it suitable for a wide range of applications. The inclusion of a PCB board with four mounting holes simplifies the installation process, allowing customers to securely fix the module onto their application products. This feature makes the WEA012864A an excellent choice for developers seeking a robust and easy-to-integrate display solution.
Built-in with the SSD1309 IC, the WEA012864A supports a 4-wire SPI interface as its primary communication protocol, with an optional I2C interface for added flexibility. The module operates with a driving duty of 1/64, ensuring efficient power management and consistent display performance. The logic supply voltage ranges from 3.3V to 5V, and the module includes a conversion circuit that allows it to handle I/O levels from 5V to 3V, making it compatible with a wide range of microcontrollers and embedded systems. The module's current consumption is 80 mA (typical value) when displaying a 50% checkerboard pattern at 3.3V VDD, reflecting its efficient power usage and suitability for low-power applications.
The OLED technology used in the WEA012864A offers several advantages over traditional display technologies. OLEDs are self-emissive, meaning each pixel generates its own light, eliminating the need for a backlight. This results in a thinner, lighter, and more energy-efficient display. Additionally, OLEDs can achieve true black levels and high contrast ratios, enhancing the visual quality of the display. The module also provides wide viewing angles, ensuring that the content remains clear and legible even when viewed from extreme angles. This is particularly beneficial for applications where the display may be viewed from various positions, such as in handheld devices or control panels.
The WEA012864A is designed to operate reliably across a wide temperature range, from -40ºC to +80ºC, making it suitable for use in both extreme cold and hot environments. This robustness ensures consistent performance in demanding applications, such as outdoor equipment, industrial control systems, or automotive displays. Additionally, the module can be stored at temperatures ranging from -40ºC to +85ºC, ensuring its durability and longevity even under harsh storage conditions.
The 4-wire SPI interface supported by the WEA012864A provides a simple and efficient communication protocol for interfacing with microcontrollers or other host systems. The SPI interface is known for its high-speed data transfer capabilities, making it ideal for applications that require fast refresh rates or dynamic content updates. The 4-wire configuration includes SCLK (Serial Clock), SDA (Serial Data), CS (Chip Select), and D/C (Data/Command) pins, which allow for precise control of the display and efficient data transmission. For systems requiring a simpler interface, the optional I2C interface provides a compact solution with fewer pins, making it suitable for designs with limited pin availability.
The WEA012864A is well-suited for a variety of applications, including smart home systems, where its high contrast and wide viewing angles ensure that information is easily readable from a distance or in varying lighting conditions. In medical devices, the module's compact size, low power consumption, and clear display quality make it an excellent choice for portable and handheld instruments. For smart control systems and metering applications, the module's durability and wide operating temperature range make it a reliable choice for displaying critical data in challenging environments.
In summary, the WEA012864A is a highly capable and versatile OLED display module that combines advanced technology with practical design features. Its 128x64 resolution, SSD1309 IC, and support for 4-wire SPI and optional I2C interfaces make it a powerful solution for applications requiring clear and dynamic visual displays. The module's wide operating temperature range, low power consumption, and integrated PCB with mounting holes further enhance its appeal, making it suitable for a wide range of industries and use cases. Whether used in smart home systems, medical devices, smart control systems, or metering applications, the WEA012864A delivers the performance, reliability, and efficiency needed to meet the demands of modern electronic designs. For detailed technical specifications and integration guidelines, designers are encouraged to refer to the module's datasheet.
