ESP32 Forum

Thank you so much for your help!
I'm just going to make it now, I don't really care anymore about antenna or a reset button, I just want the chip to work normally.

Design aside, do you have any suggestions with the soldering or anything else?

Don't burn your ESP32 but seriously, if that was how your many-times reworked PCB looks, I think you should do fine.

i have checked your schematic, you will need a USB to UART converter IC like CP2102N also for auto programming you will need a transistor combination connecting to the DTR and RTS pin of the CP2102N chip.

Thanks for the tip, but I already have made the board, plus the MCP2221 (USB to UART Converter) should work fine and I don't need auto reset.

Ok I'm back!
I received the board a few days ago, got the power supply, LEDs and the USB to UART converter working. I had a fight with the Micro USB port, so its a little crispy , but I got it to work eventually. But the chip still doesn't work, I sometimes get something back on the RX line but ESP-IDF identifies it as serial noise. So here is what I think could be a problem:
1. Diffrent Baud rate
2. Bad Soldering (large possiblity)
3. Melted chip (I thought ahead this time and got 2)
At this point a simple module is going to be cheaper...
So you guys have any ideas?

I want this board to work, but If it doesn't, I am just going to start to use easy modules.

Standard debugging steps apply here, I'd say
- Check voltages. Do you have 3.3V on all rails that need it?
- Check current use. An ESP32S3 eating up 2A is not healthy
- Check if the 40MHz crystal does something. A scope on one of the pins should show a weak, but noticable 40MHz-ish sine.
- Check if you get a bootstrap message on the UARTs TX pin if you reset the ESP32S3 using a terminal emulator
If you get to the last point, post that message here and we'll see if there's anything that points at.
