Dell LCD Display with ESP32

@Antony1 the pi02w is a pi3 in pi0 form factor.
has hdmi on board for the display , and wifi
pi02w doesn’t support a fan

any 2a power supply will be good

use the raspi imager to create the sd card
you can set it up so you don’t need keyboard or mouse to run on first boot

i would run the legacy 32 bit image
enable ssh in the config, then you can use ssh connection from your dedktop/laptop to
access

run my installer script, it does all the work
see
https://github.com/sdetweil/MagicMirror_scripts

limitations:
well smaller memory means the swap file will be used when memory gets full, sd cards are slow
but the next device up is a bigger form factor

some of the competition has started making pi0 form factor boards either more memory and faster processors (for more money of course)

this form factor only has one micro usb port, i recommend a hub w usb A ports gor mouse/keyboard

also recommend one of the free sw tools to run from you home system, winscp or bitvise ssh clients, they give you the terminal window AND a file manager view of the target pi file system so you can double click to edit the pi/MagicMirror files and drag/drop files too

@sdetweil There is a hole thread about it in the forum, I have not read any of it tho
https://forum.magicmirror.builders/topic/18194/raspberry-pi-zero-w-for-magic-mirror

maybe you find some good answers there, it´s not a new idea, I know the zero 2W from many retro consoles and handhelds atm, so it seems to be powerfull enough while light on the battery. Many of the Anbernic devices run it.

@schris88 thanks . really @Antony1 needs the info

Dear community,

Thanks again for the helpful links and tips regarding my project. I’ve now more or less completed it. The only thing still missing is a suitable flat and thin frame—then it’ll be fully done.

I’m really impressed by how well it works with the Raspberry Pi Zero 2 W. Everything runs smoothly, and I’ve been able to install all the modules I need without any issues. The whole setup is now less than 1 cm thick. With the frame, it will probably end up around 1.5 cm.

Unfortunately, I still have to run two cables—one for the display board and one for the Zero2.

Once again, thank you so much for the support! This project was a lot of fun and now gives us a great overview of daily tasks, appointments, current traffic conditions, weather, and more.

Very nice. I have done something similar, although I prefer the Pi 3 Model A+. It’s slightly bigger than the zero 2w but is clocked faster (1.4 GHz vs 1) and has a full-size HDMI port. (they both use essentially the same SoC).

Note I have historically had problems with running out of memory running electron in the 512 MB limited memory space - but using dietPI has really help stability
