Specification:
Control chip: SSD1306
Display area: 21.744 x 10864mm
Physical size: 27.3 x 27.8mm
Interface type: by Default 7-wire SPI
Switchable rear resistor to use 3-wire SPI, IIC interfaces
Number of pins: 7
Display color: Yellow and Blue
Working temperature: -40 -70°C
Interface definition:
GND (Power ground)
VCC (Power + 3.3-5V)
D0 (SPI clock line for SPI interface and IIC clock line for IIC interface)
D1 (SPI data line for SPI interface and IIC data line for IIC interface)
RES (OLED reset, OLED needs to be reset once after power-on)
DC (SPI data/command selection pin, used to set IIC address when IIC interface)
CS (OLED SPI chip select, active low, if you do not want to use must be grounded)
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 Includes:
1 x 0.96 Inch Yellow Blue SPI interface OLED Display Module
