Description

WEF012864K est un module d'affichage PMOLED passif monochrome graphique COG de 2,7 pouces avec une résolution de panneau de 128x64 pixels et un contraste élevé(10,000:1). WEF012864K dispose d'un circuit intégré de contrôleur SSD1309 intégré, qui prend en charge plusieurs interfaces de transmission : 6800, 8080, 4-Wire SPI et interface série I2C. Il utilise un pilote 3V et adopte le mode 1/64Duty.

Le module WEF012864K adopte le même panneau OLED de 2,7 pouces que le WEO012864K, mais avec un cadre en fer ajouté pour une fixation pratique par le client.

WEF012864K est un module d'affichage OLED à structure COG. Il est organique, auto-éclairé et ne nécessite pas de rétro-éclairage. Le module est mince, léger et a une faible consommation de courant. Le module WEF012864K est très adapté aux produits portables, aux instruments de mesure, aux produits ménagers, aux systèmes POS, à l'Internet des objets, aux équipements de communication et médicaux, etc. La température de fonctionnement de ce module est de -40°C à +80°C, et la température de stockage est de -40°C à +85°C.

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
