It’s available on Amazon, but it’s been out of stock on Aliexpress and the LILYGO website almost since launch.

I think the form factor of the tiny corner display proved to be junk (causing eye strain), but this one at least appears to have it centered.

Am I getting this right, no camera? That knocks off a lot of use cases.

If the other IO pins are accessible, I definitely want to buy a couple of these. A 126×126 display is a little limiting, but manageable.
