ESP32-C3 Custom PCB Design Issue - Device Not Working

[fawazapp]

Hi all,
I’ve designed a custom PCB for the ESP32-C3 SoC following all the steps outlined in the design guide document. However, the device is still not working, and I’m unable to pinpoint the problem.

I’ve attached the schematic and PCB layout images for reference.
Would appreciate any guidance on what might be causing the issue or what steps I can take to troubleshoot this further.

That is about the most useless diagnostics you can post here. In what way specifically is it not working? What did you already measure / try?

Power Supply: I’ve confirmed that the ESP32-C3 is receiving 3.3V at its VDD pin using a multimeter.
Boot Mode: I’ve checked the boot and enable pins and ensured they’re correctly connected.
