LILYGO T5-4.7 inch E-Paper ESP32 V3 Version 16MB Flash 8MB PSRAM WiFi BLE for arduino 18650 Battery Holder Version

The media could not be loaded. Disclosure - I'm just a guy trying to stay one step ahead of my kids when teaching them science, I didn't know computer science until recently. So this was a was a great find as it has a feature rich set integrated into one system. It's a High quality esp board with ePaper display, and it includes a proper USB cable. If you are good with code( which I am not), then you can do so much with it. However, for amateurs it is a hard board to find support, it took weeks of trouble shooting to get it to work... My initial plan for a weather station didn't work, the GitHub page was very problematic as code was pulled due to license issues, and vendor support is pretty non-existent. Fortunately, I was able to build a real time stock and crypto tracker by tweaking some code to fit my needs. I love esp32 boards with Arduino ide, but you may be better off sourcing different parts as support may be better. Once I got code to work, I was able to make modify a case and it turned out great. A few final thoughts ... I'm still working on low power mode with the esp board to maximize the 18650 battery life, not all public code is optimized to run on a battery .

Using this for my first ESP32 project - got up and running quickly using PlatformIO.

Easily one of best ESP32 e-paper widgets out there IMO. It's got a fast refresh and built in MCU.This is a great device, and makes a nice all in one unit for any number of hobbyist applications that would benefit from a large fast e-paper screen.I have two of these. They've even saved my bacon on a commercial project.Here are the reasons I didn't give it 5 stars:The partial refresh doesn't work as smoothly as I'd hope, but this is a problem with pretty much every e-paper device I've ever used.The SD reader adapter you can get for it doesn't seem to work at all. I've tried one on two different Lilygos of this model to no avail.This may not matter for most of you, but the device does not include a display controller. The ESP32 *is* the display controller, requiring the 2nd core and some really funky internal code to make it work. Fortunately they provide source code for the driver, and I've written my own variant.There's an S3 version out that's even less expensive, and with a bit more capable MCU.That said, none of these are show stoppers, and are relatively minor issues. The biggest deal to me is the SD reader, but it could be my reader is bad. I haven't ordered another SD reader adapter because they're relatively difficult to get one's hands on despite being inexpensive.

This was super easy to setup and get running. I had no issues with any of the demos provided. Screen refreshes fast just as described. I've been wanting to play around with an e-ink screen for a while.If you happen to upload a bunch of different test sketches you may run into an issue with the screen getting dirty looking. Just run the "screen_repair" sketch from LilyGO's GitHub page and it will clean it all up.I had some bigger plans for this but actually like the weather setup for now. I have it running off an 18650 battery and with hourly updates it should last for months. The case I 3D printed - it was convenient they also provide the CAD files for the screen to model with. Overall a fun little project and one day when I get motivated I might pick up another to display some other information like rss feeds or something.

It worked flawlessly using other people's sketches in Arduino IDE. But be aware that this epaper display has very poor to minimal documentation available. I had to learn how to use it from repurposing other people's sketches. Not a process for the faint of heart, or the new beginner in Arduino or ESP 32.That said, I have enjoyed working with it, and found it reasonably easy to repurpose to my needs. Other people have commented favorably on the display itself, and how it appears as if writing on a piece of literal paper. The image quality is very good.I particularly like the fact that they have packaged the ESP 32 together with the display and a battery connector. That makes getting over the hardware engineering phase of a new project quick and painless. The software part is where it becomes daunting. But persevere if you're so inclined, I find it to be a good piece of kit.

Using ESPHome and HomeAssistant to pull in data and display it in a user-friendly format as a sort of make-shift family info board. It is a lot of fun to tinker with. Battery life is really good the way I have it configured to deep-sleep, etc.
