Story

As we know COVID-19 disease is very serous now. I think maybe should create a small device to help me track the current situation of the world.

ESP32 is a very powerful and small board with WiFi and BLE support. It can support many kinds of arduino sensors and accessories. For the most important part, the Waveshare's ePaper driver board include a raw FFC slot can be used to connect with many ePaper module.

For the display part, I choose the 2.9 inch module so it small enough to setup it anywhere.

BTW: Event I'm using a 3 colors module so I can show some information as RED color, not just the normal black and white. But finally, I found that it's a bad idea really. The 3 colors module's speed is very slow, almost need 10~20 seconds to refresh all the screen, and it did not support part refresh. So, if the color is not a big thing, maybe the normal B/W e-paper screen is a good one.
