VCC: 3.3V~5.5V GND: GND DOUT: Serial port data transmission DIN: Serial port data reception WAKE_UP: External wake-up pin RST: External reset pin.Īfter powered up, the screen is refreshed to white. With the host computer software, the display can be completed directly by using the computer.Į-book reader, shopping mall POS, shelf label, industrial instrument display. 5V, the logic level is compatible with low power consumption, the current is less than 5mA after the system sleeps. After the system is powered on, the default is 115200. The serial port baud rate can be customized. The font library and picture data can be stored in the external TF card, or imported into the internal NandFlash 4-level grayscale display, with a resolution of up to 800 × 600. Built-in font library supports 32, 48, 64 dot matrix GBK Chinese font library 32, 48, 64 dot matrix English font library has built-in 128MB NandFlash. It is easy to use, only one serial port is needed to complete the display, including drawing geometric figures and displaying text and pictures. Just one serial port can realize all functions, free you from complicated details and release your creativity. If you don't want to learn the complex details of the bottom of the e-paper screen and don't pay attention to the specific display algorithms of graphics, text and pictures, then this product is born for you.
