Custom ESP32-C3 PCB won't connect via USB (no Port)
Posted: Thu Oct 13, 2022 5:46 pm
Hello everyone,
I recently made a custom PCB for an ESP32-C3-FH4 but if I connect it to my PC there is no port found for the board. I am using the onboard USB Interface as you can see and the crystal is an ECS-400-10-37B2-CKM-TR (40MHz, 10ppm, CL=10pF). I have no Idea why it wouldn`t work as this isn’t my first PCB design either and the circuit is pretty much the same as on all the other designs I found online. I tried resoldering it a couple of times, use different Load Capacitors for the Crystal and measured voltages on the inputs to ensure the SOC has voltage, but nothing works. Am I missing something? And yes, there are a lot more components on the board including a power supply, but they are irrelevant for that matter and for the sake of testing I haven’t soldered them to the board (except the supply circuit) to ensure errors in the schematic of other components (which there probably aren’t any because I build circuits for all other parts like a million times) won’t affect my Esp32 circuit.
Thanks in advance,
Niklas

But that alone didn't fix my problem. VDD_SPI acts as a power source and not a power input and since I had it connected to 3.3V the thing didn't connect to my PC.
