Re: ESP32-S3 PCB Design Problems

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 E...

Re: ESP32-S3 PCB Design Problems

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.

Re: ESP32-S3 PCB Design Problems

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?

Re: ESP32-S3 GPIO3 does not select external JTAG when low

Hello there! Please make sure your EFUSE values are set properly: EFUSE_DIS_USB_JTAG = 0 EFUSE_DIS_PAD_JTAG = 0 EFUSE_STRAP_JTAG_SEL=1 Setting these "should" make sure that you can set the GPIO3 Strapping pin. You could also permanently set it to External JTAG using: EFUSE_DIS_USB_JTAG = 1 EFUSE_DIS...

Re: ESP32-S3 PCB Design Problems

Whelp screw it, i'm going to design another board, the test did not work although something happened. The regulator died randomly but before that, I saw some activity on the Uart Tx pin on my USB to Uart adapter, maybe meaning the test would of worked if I hadn’t done so much with the chip? Anyways,...

Re: ESP32-S3 PCB Design Problems

Ok! I'm back! Sorry for the delay. I have lots of projects to work on and so it took me a while to get back to this project. After soldering the 10k Ohm resistor on to the board I realized that I don't have any extra 1uF caps lying around, so I wonder if I can do the following: 1. Desolder the 10k O...

Re: ESP32-S3 PCB Design Problems

You're absolutely right! I need to take out the reset switch and put in the 1 UF Capacitor to create the RC Circuit! I'll do that in a bit... Yeah, although, my board is less crunchy than the previous prototype. :shock: Yes the pins always read the correct voltage, I've been tested that since day 1....

Re: ESP32-S3 PCB Design Problems

Hello there! Thanks for responding! I'm honestly really new to ESP and PCB design but I have plenty of experience with stm32 and Kicad (weird but true). Here are my files: ESPUSB_sch.pdf ESPUSB_PCB.pdf I honestly want to note that this could also be a soldering error or the fact I bought the chip fr...

ESP32-S3 PCB Design Problems

Hello All, I would like to thank anyone in advance for helping me solve my problems, if you can. ;) Recently I had tried to create my first PCB using the ESP32 S3 but in my smarts, I decided to not use the module but instead use the chip directly, which was the start of my problems. Then after desig...
