Precautions: Please avoid long-time high-frequency refresh when using it. The recommended refresh interval is (15s/time). Do not expose to ultraviolet rays for a long time, otherwise it may cause irreversible damage to the ink screen. The low-power power management solution adopted by CoreInk is different from that of CORE and StickC devices. When in use, the PWR button is used as a power-on button(long press 2s). If you need to shut down the device, you need to use the software API or press the reset button on the back.

i got these for temperature monitoring because the m5stick gets too hot, these units are a perfect and do not elevate the ambient temperature, resulting in an accurate reading. I can't wait until M5 comes out with a color version of e-ink for these!

A neat remote controller for your M5Stack based home control environment
A really nice and easy programmable device. Leave it on your table and it will be powered nearly forever. My only suggestion is to optimise the casing and turnwheel for more handheld satisfaction. It feels a bit uncomfortable. But hey, it is great.
