Feature

●*Driver IC: SSD 1306
●* Brightness: Supports 256 levels of adjustable brightness
●* Communication Interface: IIC interface
●*Special Note: The screen drive chip supports internal boosting, so it can provide direct power supply. No external high pressure power supply required
●* If you use an internal boost, the 6 foot long VCC does not need to connect to a power supply. Simply connect the capacitor directly to the ground. When using an external power supply, the VPP needs to be connected to a power supply of about 7.5V rather than 3.3V
