#Designed a desktop stand for my $20 touch screen esphome display

I picked up a guition-esp32-s3-4848s040 touch screen for esphome, been very happy with it, but the form factor is meant to be wall mounted, so I drew up a desktop stand

Installing involves removing the existing case, there's a small amount of sticky tack (not strong glue) around the silver wall case, with some pressure it pops away. You'll want to add some rubber feet or weights inside to stop is sliding when touched.

The code can be found here on GitHub (https://github.com/jtenniswood/esphome-lvgl/tree/main/guition-esp32-s3-4848s040), it was based on this post (https://community.home-assistant.io/t/guition-4-480x480-esp32-s3-4848s040-smart-display-with-lvgl/729271) but with further customisation, as I originally used it with a 7inch display.

I still need to figure out the wiring to get power connected from the back, I just haven't got the right connectors to install a usb-c port at the back, to make it a cleaner design.

You can inject 5V on the 8-pin connector on the back. Doesn't need to be fancy.

Yes I was hoping that was true. Just don't know what the right connector is. Any idea?

Pinout is available, it's just 0.1" headers into the 4x2 header on the back.

Is this the display?

Looks like it. Price should be as low as around $15, without any relays (ie. if you don't need mains power, or to switch anything)

#

Then I will need an external power supply?

dire parcel
#

sure, depends on how you are planning to use it. If it is to be a wall display, and you have a convenient mains outlet nearby (e.g. a light switch box, and are happy working with 240V, then by all means get the 1-relay one. If it is going to be a desk display, then maybe the one without the relay will be what you want. Of course, you can easily remove the relay, so spending a little more for the flexibility may be worth it for you.

Is there any way to directly to the wall?

dire parcel
#

if you get the one without the relay, you will need to give it 5V from e.g. a USB charger

#

depends on how you want to power it. It doesn't have any mountings for direct wall mounting. And if you get the relay, it sticks out the back by 2cm or so.

#

but you could use some double sided tape to stick it to the wall , and run a USB-C cable to it without any trouble.

I have a wall outlet nearby

#

So 230v

Problem is that there are no screw holes. And no way to get to the holes with the display in the way

#

well, to be accurate, there are two TINY screw holes on the back of the display module, but it is designed to clip onto a backing plate, which the relay comes with.

#

You could possibly replicate something with 3D printing, because there are small notches that the display unit includes, but your design and printing will need to be very accurate to have a press fit.

#

That you can then remove again when you need to.

#

And how do I connect it directly to the wall outlet?

#

I have to use a adapter anyway right?

dire parcel
#

yes

#

well, as I said, you could use double sided tape, as an option

#

This is what it looks like from the back

#

You can see the two tiny screws that I mentioned, which you could possibly use. (Top left and right corners, silver). But then your bracket would need to screw onto the box somehow.

#

If you want it to go onto a box, I would get the 1-relay version and power it using mains. OR, you could reuse the plastic adapter plate, and just remove all the electronics/relay, and power it using 5V to the 4x2 header in the top left corner.

#

Also not a terrible option, to be honest.

#

either way, get the 1-relay option, I guess

#

It will be a lot more obvious once you have it in your hands

digital iris
#

Something like this should also be possible right?

dire parcel
#

PRobably

digital iris
#

I see that it is pretty big on the back with the relay

dire parcel
#

Yes, I think I mentioned that. That is why you need a box for the relay to go into.

#

And if you get the relay, it sticks out the back by 2cm or so.

digital iris
#

maybe i will not get the one with the relay i guess

digital iris
#

Are these the 5 cables?

dire parcel
#

I’d suggest getting the relay anyway, actually. It’s a relatively small amount of money, and opens up options for mounting using the plastic shell/plate that might be tricky to replicate with a 3d printed alternative.

Nice! That is amazing!

#

Exactly what I wanted
