Descripción

WEF012864K es un módulo de pantalla COG gráfico monocromo pasivo PMOLED de 2.7 pulgadas con una resolución de panel de 128x64 píxeles y alto contraste(10,000:1). WEF012864K tiene un controlador IC SSD1309 incorporado, que admite múltiples interfaces de transmisión: 6800, 8080, 4-Wire SPI e interfaz serie I2C. Utiliza un controlador de 3V y adopta el modo 1/64Duty. El módulo WEF012864K utiliza un panel OLED más grande que los módulos WEF012864G y WEF012864H de la misma serie, pero agrega un marco de hierro para facilitar a los clientes la fijación de la estructura. 3V sürücü kullanır ve 1/64Duty modunu benimser.

El módulo WEF012864K adopta el mismo panel OLED de 2.7 pulgadas que el WEO012864K, pero con un marco de hierro añadido para una fijación conveniente del cliente.

WEF012864K es un módulo de pantalla OLED de estructura COG. Es orgánico, autoiluminado y no requiere retroiluminación. El módulo es delgado, ligero y tiene un bajo consumo de corriente. El módulo WEF012864K es muy adecuado para productos portátiles, instrumentos de medición, productos para el hogar, sistemas POS, Internet de las cosas, equipos de comunicación y médicos, etc. La temperatura de funcionamiento de este módulo es de -40°C a +80°C, y la temperatura de almacenamiento es de -40°C a +85°C.

14 NC No connection
15 CS# This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW (active LOW).
16 RES# This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin pull HIGH during normal operation.
17 D/C# This pin is Data/Command control pin connecting to the MCU. When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data. When the pin is pulled LOW, the data at D[7:0] will be transferred to a command register. In I2C mode, this pin acts as SA0 for slave address selection. When 3-wire serial interface is selected, this pin must be connected to VSS.
18 R/W# This pin is read / write control input pin connecting to the MCU interface. When 6800 interface mode is selected, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH and write mode when LOW. When 8080 interface mode is selected, this pin will be the Write (WR#) input. Data write operation is initiated when this pin is pulled LOW and the chip is selected. When serial or I2C interface is selected, this pin must be connected to VSS.
19 E/RD# This pin is MCU interface input. When 6800 interface mode is selected, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled HIGH and the chip is selected. When 8080 interface mode is selected, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected. When serial or I2C interface is selected, this pin must be connected to VSS.
20~27 D0~D7 These pins are bi-directional data bus connecting to the MCU data bus. Unused pins are recommended to tie LOW. When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 will be the serial data input: SDIN and D2 should be kept NC. When I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin in application and D0 is the serial clock input, SCL.
28 IREF This pin is the segment output current reference pin. IREF is supplied externally.
29 VCOMH COM signal deselected voltage level. A capacitor should be connected between this pin and VSS.
30 VCC Power supply for panel driving voltage. This is also the most positive power voltage supply pin.
31 NC(GND) No connection
