Hi all.
I got a ESP32S3 board:
https://vi.aliexpress.com/item/1005004139658436.html?spm=a2g0o.order_list.order_list_main.192.257f1802VBsMOq&gatewayAdapt=glo2vnm
and ST7789v 1.69" TFT:
https://vi.aliexpress.com/item/1005005238299349.html?spm=a2g0o.order_list.order_list_main.222.257f1802VBsMOq&gatewayAdapt=glo2vnm
and I am trying to make PCB board to test them.

the only thing I awarded for now is remain IO19/20 for USB port, what else do I need change?

the layout: ESP32 S3 ST7789 V — Postimages

Thanks
Adam

Actually that is not a (dev) board, it's a module. You will need a couple more of things in your PCB. You should read the ESP32-S3 module datasheet carefully:

For example in the section 6, Peripherals, you have a description of the common elements that you would need in the PCB:

Like the USB connector, decoupling capacitors, reset button, etc. Some are optional. You should decide how will you power it, programm it, etc.

If all you want to do is confirm the ESP32 is working, buy an inexpensive test/programming jig like this:

  • Also, if you do not have good soldering skills you will to practice a lot.
    See this YouTube video:
  • Getting the camera to work is another game you need to master.

Thanks.
Yes, I'll need to add somethings. actually the idea from atomic14's video, try to test ESP32SE little by little.

it's a nice process.

Thing here is I am not sure that if some pin have special useage like the pin IO19 and IO20 which good for directly to USB. or if ST7789v need some special pin?

Great!
I'll order the ESP32 programmer.
I'd ordered hot plate and solder paste.

  • The YouTube soldering example above does not use a hotplate.
