Feature:
Control chip: SSD1306
Display area: 21.744 x 10864mm
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: yellow 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:
5 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
