Originally I was just using it to display the IP addresses after reboot on a smaller 0.96" 80x160. Then a screen shot... then zoom. I'm thinking more about some QR code with basic sysinfo.

QR for status or info on anything is the winner here...

can you array these off a single PI?

Imagine this:

An installation where there is an array of these screens - they are associated with whatever you want info on - they cycle btwn a screenshot of the item, some basic text (like IP/UPC/Barcode/QR to a fully detailed product/item page, uptime/health status...) etc...

And you can just have a PI running a bunch of these on a 42" rack, or on shelves of retail items etc....

This is a good question. You should be able to control multiple SPI devices at the same time, but that requires the CSX/CS ("Chip Select") pin to be present. The model I bought doesn't seem to have this feature, but someone found a hack [1]. I will add this info to the readme as you're really better off buying displays with CS if you're planning to control multiple tiny screens. [1] https://www.instructables.com/Adding-CS-Pin-to-13-LCD/

You can probably do this off an esp32 without too much trouble.

Please educate me on where I should go for esp32?
