Let me quote them:
M5Stack has just launched its unique and latest core device with a touchscreen e-Ink display. M5Paper ESP32 IoT Development Kit is a fully programmable microcontroller-based platform that can be an ideal choice for your IoT applications. This low-power device could suit such purposes as an industrial controller or smart weather display
Would be really interesting to see projects coming out of this new kit. It certainly offers a lot of properties which look quite interesting.
