You don't see this very often on this channel: an E Ink or e-Paper display. It's the smallest I could find. If you remember in the past, I used some bigger E Ink displays like the Lilygo T5, M5Stack Epaper, a soldered 6" display, and a soldered 10".
E Ink displays are usually bigger, and the reason why I don't use them more often is that they are slower than LCD or AMOLED displays. But they have they place in game.... stay tuned and you will find why!

Love your videos! You inspired me to get a T-display-s3 and I love it!

@7zzZKnightZzz7

I love your projects. I learn so much from them and I wish I had your ideas. Thank you for releasing these videos and the code to help us all learn.

@Rob_65

The board is awake for 2s, so this results in 28 mA during 2/60 of the time and 1.25 mA during 58/60 of the time. So this averages out to a current of 2.14 mA. 500/233 is 233.463 hours or 9d17h27m but this will more likely be 7d18h46m due to the fact that the battery reaches a voltage below 3.3V when discharged 80% and most likely the board will then stop working

@Zortan12

Love your stuff

@matthewwain9958

Shame these displays are relatively expensive. Would have been nice to have used them in a project I have where I wanted to keep a count, and status flags.

@MarcelDiane

How do you do battery level monitor?

@PauloFurlan-Lumens

Adorei a ideia, já vi algumas etiquetas de preço, com essa tecnologia, será que podemos colocar um esp32 com uma etiqueta destas???

@bartdepauw1156

500mAh = 30000mAm

@Co0kez

hi volos, could you make a project for example a flipper zero with your own hands, you just have a huge talent in terms of technology, thank you if you read😃

@charleswatt4397

I have done ESP32 clocks using the internal RTC and I update from NPT server once or twice per day to keep accurate.

@alejandroperez5368

1.2mA when sleeping?

@goranjosic

Volos, shouldn't a version with T-U2T last longer, considering USB chips often draw batteries when in sleep - i know lilygo has become very good at making low power devices, and it's possible they've solved this problem (looks like they managed it on some of the esp32 boards).
