1.54inch SPI OLED Module SKU:MSP154X

== Product Picture ==
==Product Description ==
* 1.54 inch OLED screen with black and white, black or blue or yellow and blue color display
* 128x64 resolution for clear display and high contrast
* Large viewing angle: greater than 160° (one screen with the largest viewing angle in the display)
* Wide voltage supply (3V~5V), compatible with 3.3V and 5V logic levels, no level shifting chip required
* The default is 4-wire SPI bus, which can choose IIC bus
* Ultra-low power consumption: normal display is only 0.06W (far below the TFT display)
* Military-grade process standards, long-term stable work
* Provides a rich sample program for STM32, C51, Arduino, Raspberry Pi and MSP430 platforms
* Provide underlying driver technical support

NOTE:
:1.This module supports IIC and 4-wire SPI interface bus mode switching (shown in red box in Figure 2). The details are as follows:
::A.Using 4.7K resistance to solder only R5 resistors, then choose 4-wire SPI bus interface (default);
::B.Using 4.7K resistance to solder only R4, R9 resistors, then select the IIC bus interface;
:2.After the interface bus mode is switched, you need to select the corresponding software and the corresponding wiring pins (as shown in Figure 1) 
::for the module to operate normally. The corresponding wiring pins are described as follows:
::A.select the 4-wire SPI bus interface, all pins need to be used;
::B.select the IIC bus interface, connect GND, VCC, SCL, SDA and RES, and connect DC and CS to power ground 
:3.Weld R8 (as shown in the green box in Figure 2), then the CS pin is grounded, and this pin does not need to be connected
Number	Module Pin	Pin description
1 	GND 	OLED power ground
2 	VCC 	OLED power positive (3.3V~5V)
3 	SCL 	OLED SPI and IIC bus clock signals
4 	SDA 	OLED SPI and IIC bus data signals
5 	RES 	OLED reset signal, low level reset 
(this pin need to connected to the high level (can be connected to the VCC) when selecting IIC bus)
6 	DC 	Select SPI bus as command/data input selection signal, high level: data, low level: command;
When IIC bus is selected, this pin can be used to select IIC slave device address. Select 0x7A for high level and 0x78 for low level;
7 	CS 	OLED chip select signal, low level enable 
(this pin need to connected to the power GND when selecting IIC bus)
