IR Touch Frame calibration]]]]
-
I’ve been searching through the hardware portion, but I couldn’t find something that really said that would be great an IR frame, or a touch-file. I was planning to use RPi3, but if I need more power, I’m going to get aboard. Also, I haven’t bought any glass or screen yet, seeing that they might not be compatible.

I got 43 inch IR frame from aliexpress, it took a bit to track down calibration steps. It basically worked out of box just plugging into pi 4.
I’m powering directly from pi also, seemed ok.
I’m not at home but can add more detail and link to how to calibrate, once back in couple days.

Update
I used this guide to setup calibration:
