I've been experimenting with different types of display so I thought I'd try E-paper for the first time. Disclaimer - I am no expert and I have not studied all the documentation - I am just tinkering as a hobby and I want to display my own weather station information and also display information from Home Assistant . I am very pleased with this device and the support I've been given. I needed help to find the weather example - I got an email back the next day from LilyGo and I now have it up and running. If you try this yourself do follow the instructions to the letter - it took me about 3 goes and the failed attempts were caused by my errors in following the steps. In my opinion the device is very well made and the design gives a lot of attention to detail. You can run it off the usb port and there is a charging circuit for the battery so you can treat it like a mobile device - just plug it in for a charge. There are 5 buttons on the top and I've not yet worked out what they do. I'm thinking they could be used to toggle between different views and increase the range of information that can be displayed. I've ordered a 1000MAH battery and it will be interesting to discover the battery life. I think the display is easy on the eye and of course so different to a normal bright LCD screen. The resolution is so high it has the potential to display a lot of information. It does need light to view. I have yet to explore the full potential of the screen and I can't comment on the longevity but I'm very pleased with the product. One question I'm not sure about is where it has any touch capability. I didn't think so when I bought it but there is a touch example which I haven't tried- perhaps it would be useful if someone else could comment. I'll need to design a case and it would be great if people would share 3D print designs as inspiration and save time.

Graham Use a USB to serial converter set to 3.3V. Wire it to the RXD and TXD pads on the board. Ground GPIO0 when powering up to put it into flashing mode. I'm going to get one to try.
