What type of monitor are you using?

What type of monitor are you using? What size is it, what are the correct connector types, and what are its specifications? I need to find that information.
I asked if using the connector pins of this monitor was correct. https://shopee.vn/1.3-Inch-1.3-TFT-Full-Color-LCD-Display-Module-18Pin-HD-IPS-LCD-M%C3%A0n-h%C3%ACnh-LED-240-*-240-SPI-8Bit-8080-MCU-Giao-di%E1%BB%87n-song-song-ST7789-i.1156302552.29980791485

I cant see the one you shared but the one you need looks to be a standard 1.3in ST7789 IPS TFT, you need the a 12 pin version

I haven't built the updated version yet as I am waiting on the PCB to arrive but these are the displays I just ordered;

You could also order the ones with the full module and just remove the display and reattach it to your PCB, for example this one;

I received my PCB and displays, the vendor on Aliexpress sent me the wrong display model but I can confirm the displays from Alibaba worked.

Though I did have to spend a few hours to figure out the correct user config for the TFT_eSPI library to work correctly before mine would actually work
