I have ESP32 S3 zero and it has a usb type-c female port on it, but my project needs USB A male (like a flash drive). I am afraid I don't have enough skill to desolder the default port and solder thin wires where needed. Can I use pins for that? After everything it must still work as HID device, so yes, I need USB data lines ---

Would be easier: ![image](https://europe1.discourse-cdn.com/arduino/original/4X/c/1/6/c169486738b297ba032675957b8adeb5951738fe.png) But if you like tinkering: _"GPIO19 and GPIO20 can be used as D- and D + of USB respectively. It is recommended to populate zero-ohm series resistors between the mentioned pins and the USB connector. Also, reserve a footprint for a capacitor to ground on each trace. Note that both components should be placed close to the chip._ _Note that USB\_D+ will have level output, so please add a pull-up resistor to determine the initial high-level output voltage."_ ---

Yeah I thought about using such thing but I need to keep size really small so it wasn't a good solution. Thanks for the info about GPIO 19 and 20! Why 0-ohm resistors? It's just like adding a wire, am I wrong? What capacitance should capacitors have? And pls can you explain about the pull-up resistor? Should I pull to 5V or 3.3V? What resistance? Thank you so much!!! ---

That's what Espressif writes on S3 datasheet. But if you have a look at schematic of their Devkit, they don't have caps, neither pullup. ---

I was just about asking you for the source. Okay, I'll work on it myself from this point. Marking as solved, have a nice day ---
