Circuitrocks Oled I2c Module Lcd Display Screen 0.91 0.96 1.3 Inch Blue Communicate For Arduino Phone

This OLED display module is small, only 0.96” diagonal, it is made of 128x64 individual OLED pixels, each one is turn on or off by the controller chip. It works without a backlight, that is, in a dark environment, the OLED display is higher compared to that of an LCD display, you will like the miniature for its crispness. The Driver chip of this OLED is SSD1306, which is compatible with IIC or SPI communication. So this module can be controlled by SPI or I2C. There are 2 resistors at the back of the module and sick-screen to remind you how to set the communication mode, the default mode is 4-wires SPI mode. That is, except for the VCC and GND, 4 wires would be needed when using 4-wires SPI mode. You can also set to the I2C mode, in which mode 2 control wires are needed. There is also a simple switch-cap charge pump that turns 5v into a high voltage drive for the OLEDs, making this module the easiest way to get an OLED into your project.
