2.42inch SPI OLED Module SKU:MSP242X

Product Picture

2.42” OLED monochrome screen, equipped with three monochrome displays: white, yellow, and blue
128x64 resolution, clear display effect, high contrast
Large viewing angle: greater than 160 ° (the screen with the largest viewing angle in the display screen)
Wide voltage power supply (3V~5V), compatible with 3.3V and 5V logic levels, without the need for level conversion chips
By default, 4-wire SPI serial bus is used, supporting switching to IIC bus
Equipped with an iron frame, it can effectively protect the display screen
Ultra low power consumption (much lower than TFT display screen)
Provide rich example learning programs (ESP32/STM32/ Arduino/C51/CH32/RaspberryPi)
Provide low-level driver technical support, and update WIKI information online
Multiple tests for module aging can meet military level standards, supporting long-term stable work

Number	Interface	Function Description
①	7 Pin Header	2.54mm spacing row pins, module signal input pins
②	Communication Interface Switching Resistor	If only R5 resistors are welded, use SPI communication interface (default) If only R4 and R9 resistors are welded, use the IIC communication interface
③	CS Pin Grounding Resistance	R8 resistors are not welded by default. If the R8 resistor is welded, the CS pin can be suspended

Number	Pin Label	Description
1	GND	OLED screen power supply ground
2	VCC	OLED screen power supply positive pole (connected to 5V/3.3V)
3	SCL	Using SPI interface: SPI bus clock signal Using IIC interface: IIC bus clock signal
4	SDA	Using SPI interface: SPI bus to write data signals Using IIC interface: IIC bus data signal
5	RES	OLED screen reset control signal, low-level reset (if using IIC interface, this pin can be left unchecked and connected to 3.3V high-level)
6	DC	Using SPI interface: OLED screen command/data selection control signal (high level: data, low level: command) Using IIC interface: The IIC bus selects signals from the device address (high level: 0x7A, low level: 0x78, which can be controlled by the master GPIO or connected to 3.3V high level or GND)
7	CS	OLED screen chip selection control signal, effective at low level (if R8 resistor is soldered, this pin can be suspended. If R8 resistor is not soldered, when using IIC interface, this pin must be connected to low level, which can be controlled by master GPIO or GND)
