DollaTek 2Pcs 7Pin 0.96 Inch OLED Display 12864 SSD1306 SPI IIC Serial LCD Screen Module for Arduino - Blue Font

Feature: Control chip: SSD1306 Display area: 21.744 x 10.864mm Physical size: 27.3 x 27.8mm Interface type: Default 4-wire SPI Switchable rear resistor to use 3-wire SPI, IIC interfaces Number of pins: 7 Display color: Blue Working temperature: -40~70°C Net weight: 5g Interface definition: 1> GND (Power ground) 2> VCC (Power + 3.3-5V) 3> D0 (SPI clock line for SPI interface and IIC clock line for IIC interface) 4> D1 (SPI data line for SPI interface and IIC data line for IIC interface) 5> RES (OLED reset, OLED needs to be reset once after power-on) 6> DC (SPI data/command selection pin, used to set IIC address when IIC interface) 7> CS (OLED SPI chip select, active low, if you do not want to use must be grounded) Package includes: 1 x 0.96 Inch OLED Display Module Wiring method: Wiring 1: MCU hardware SPI connection method: If there is only one device on the SPI bus, you can directly ground the CS of the OLED screen, which saves an IO. Wiring 2: MCU IO analog SPI connection mode: If there is only one device on the SPI bus, you can directly ground the CS of the OLED screen, which saves an IO. Wiring 3: MCU analog IIC connection method: IIC address: DC is low = 0x78 DC is high = 0x7A Generally DC grounding Wiring 4: MCU hardware IIC connection method: IIC address: DC is low = 0x78 DC is high = 0x7A Generally DC grounding Package include: 2 x DollaTek 7Pin 0.96 Inch OLED Display 12864 SSD1306 SPI IIC Serial LCD Screen Module for Arduino
