I just got a Guition JC-ESP32P4-M3-DEV board thinking it would be ideal for a number of projects I have in mind. Whilst it is easy to program and easily performs the APPs I have written I cant find a 4 or 5 inch touch display to connect to it. The only compatible display is 10.1 inches - far too big for what I want. I can control it via Bluetooth from an APP on my Android phone but I really would like to use the built in 15 pin DSI controller to make it stand alone. Does anyone know of suitable LCDs or is there any useful documentation detailing how to drive generic displays through DSI?
Dicky.

“DSI” just says it’s a MIPI DSI logical interface; manufacturers vary in lane count (1/2/4), D-PHY voltages, and whether they use the Raspberry Pi 15-pin FFC pinout or a custom connector. Confirm the lane count in the panel’s datasheet.

This board has a MIPI DSI 2 lane 15 pin FPC connector which (I believe) will handle the LCD and touch.
Thank you for the doco link.
