Features:
This OLED display module is small, only 0.96inch diagonal, it is made of 128x64 individual white OLED pixels, each one is turn on or off by the controller chip.
The driver chip of this OLED is SSD1306, which is compatible with IIC communication. So this module can be controlled by I2C. That is, except the VCC and GND, 2 wires would be needed when using 4-wires I2C mode.
There is also a simple switch-cap charge pump that turns 5v into a low voltage drive for the OLEDs, making this module the easiest ways to get an OLED into your project.

Applications:
MP3, MP4, watch, head-mounted displays, meters and other intelligent instruments. Design any pretty patterns for your beloved electronic devices.
