Graphical 128×64 dot matrix display.
Since this LCD only supports 3.3V I0 level, when using the UNO system board, as UNO can only be set as push-pull output, its L0 maximum output is 5V 30mA, which will lead to LCD level identification error and even burn the LCD screen. Customers who use UNO are not recommended to buy this product. Please understand and understand. Other microcontroller uses 3~5V normal operation!)
The module does not have any font library, the content that needs to be displayed can be programmed by the user.
