Cute and I'm glad someone is doing that, but it's too small and out of proportion for tournaments etc. You want squares of about 2.25 inches and king height of 3.75 inches, about. If you're going to all the trouble of magnetic sensors and whatnot, you might as well make the board and pieces meet the relevant standards.
These days, image recognition is good enough that it's probably feasible to just video the chess game on a non-sensory board, and let software figure out what moves were played. In cases of doubt or dispute (blitz scrambles), humans can examine the video.
If anyone cares, the tournament sensory sets that most organizers use are made by DGT and cost around $600 iirc. The magnetic sensor system is very clever and was patented in the 1990s or so, but the patents would be expired by now.
Maybe I’m missing something, but why have a single piece PCB instead of individual parts with a 3D printed slot for the sensor and LED.
A few wires later and a model scale up and your chess board can be a different size.
I suppose one piece is easier and cleaner, just less flexible.
A comment from the article:
"I appreciate your work, but that AI generated image is very disturbing and shouldn't be promoting your own work, which is so much more than an AI slab."
I've been thinking about something like that for a while but never got to working on it: having to design, order and wait for a pcb to get fabricated and shipped half way across the world, only to find out that you messed something up is insanely off putting. I so wish this process gets democratized in the future the way 3d printing and laser cutting did ~10 years ago.

Is no one going to mention that the first picture is AI generated tosh? I understand that generating a picture is easier than taking a nice picture, in a nice place with a a nice camera - but the back row of the board is all white and the second row.. sort of disappears!
