TL:DR: I don’t know how, but it no longer works.
In the previous post, I shared the joy of making #ESP32 #Lilygo T5 2.13′ e-ink display finally work and show some sensor data from #homeassistant. The joy lasted only a week.
Yesterday I decided I’d print a nice case for it.
I found a great .stl on Thingverse (a snap case), printed it and carefully put the board in it.
Then I connected the USB power and … nothing.
The screen doesn’t turn on anymore. It shows three thin horizontal lines.
Otherwise, the board works okay – I checked the logs in ESPHome – and it shows no errors.
I also noticed one of the elements on the board gets hot (maybe I didn’t notice it before).
I’m not sure what caused the failure. Maybe static electricity when I handled the board, maybe I pushed too hard when I inserted it in the case (but I didn’t push hard).
I searched if the screen could be replaced but found no useful info. It is glued to the board.
Maybe I’ll repurpose the board for something that does not need a display.
There goes 25€.
Few days later…
I was able to unstick the display from the board.
Looks good, not sure where the problem is.
Ordered a new one on #waveshare.
I broke it off, scratched the glue with an Olfa knife and cleaned it with isopropyl. Now it waits for a new screen.
The board still runs as it should – I can connect to it and see the logs in Home Assistant.
Update (29. 2. 2024) – a new display!
I’ve ordered a new e-ink display (actually, 2 – one glass and the other flexible one) at Waveshare. Yesterday I received them.
I connected them to the board and …
… nothing.
Damn.
It looks like something else is wrong. Now I have 2 spare e-ink displays :(.
