GooDisplay 2.13 Inch E-Paper Screen with Demo Kit Flexible 4 Grayscale E Ink Display Electronic Paper Display Panel Partial Refresh with Communication Board Development

as you might know a paper displays are useful for specific projects that require low power consumption or if you don't want to display the generate light which both are important characteristics that I want for my Youtube subscriber cleaner they are making but it wasn't easy to figure out how to use the display to make things easier for you I'll go through my example sketch so you can use it as a template for your projects first choose your board right now I'm using the Arduino Nano but this example sketch also works with other boards like the esp8266 and the ESP 32 second select your display many of these plates are only compatible with 3.3 volts devices so I recommend to buy one that is also compatible with 5 volts I bought this one that does support 5 volts logic if your display doesn't support 5 volts and you want to connect to Arduino then you need to put a level converter between
