Operation

The product WiKi on DFRobot website really helped me a lot.

First, we need to draw a monochrome bitmap image on the drawing board of Windows. And then convert the image into arrays via the software lcd-image-converter.exe in the WIKI. The arrays are the code of the program. So I will just skip over it here.

Click FireBeetle Covers-ePaper Black&White&Red Display Module WiKi for more details. After burning the program, we could print out our work though 3D printer and assemble all parts together. Then install a pin on the name badge. That’s all!

This is my work. It’s interesting, right! Just start to DIY your own name badge!
