A few viewers were asking about the display that I use in the CTRL ONE, so here you go! The TL;DR is that they're manufactured by Dalian Good Display in China, and the CTRL ONE is entirely built around it.
The manufacturer does sell a dev kit, but if you want a PCB that's designed around this display and connects to it perfectly, you can pick up a CTRL ONE here:
It has a modular add-on system and fully open source mounting solution while running ESPHome, so you can use it as a base for your next DIY project.
