Descrição

WEF012864K é um módulo de display COG gráfico de 2,7 polegadas monocromático passivo PMOLED com uma resolução de painel de 128x64 pixels e alto contraste(10,000:1). WEF012864K possui um controlador IC SSD1309 integrado, que suporta múltiplas interfaces de transmissão: 6800, 8080, 4-Wire SPI e interface serial I2C. Utiliza um driver 3V e adota o modo 1/64Duty.

O módulo WEF012864K adota o mesmo painel OLED de 2,7 polegadas que o WEO012864K, mas com a adição de uma moldura de ferro para uma fixação conveniente do cliente.

WEF012864K é um módulo de display OLED com estrutura COG. É orgânico, autoiluminado e não requer retroiluminação. O módulo é fino, leve e tem baixo consumo de corrente. O módulo WEF012864K é muito adequado para produtos portáteis, instrumentos de medição, produtos domésticos, sistemas POS, Internet das Coisas, equipamentos de comunicação e médicos, etc. A temperatura de operação deste módulo é de -40°C a +80°C, e a temperatura de armazenamento é de -40°C a +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
