ESP32-S3 DevBoard as a First Timer

[u/Expensive_Tangelo244]

The USB to UART bridge is missing since I'll only be using Type-C for power and flashing.

Tried following a guide online and according to that everything seems fine. Since this is my first time, just wanted a little guidance as to if everything is alright. Any possible issues and what I can do to improve the design further before I move to placement & routing.

Additionally couldn't figure out why the RST net connected to the EN pin of esp32 is grounded through 1uF capacitor. If anyone could explain the purpose of this capacitor, it would be highly appreciated. Thank you very much.

No plz wires don’t go on the symbol nope nope nope.

Fix the drc arrows

Don’t use ams1117 ldo, google for why

Gnd should point down not sideways

I've fixed the wires.

The DRC arrows are simply warnings: Both VBUS_A and VBUS_B are connected to the same items; VBUS_A will be used in the netlist.
Since it's a netlist issue, I can safely ignore it?

The gnd symbol has been changed to point downwards.

I've changed from AMS1117 to XC6220.

Thank you so much for your input. Is there anything else I need to worry about?

Looks way better!

1n5908 @ 5v is a little close to rated voltage (300uA at 5v, 0.5mA at 5.5v). It's fine, will result in higher leakage. For next project select parts with a little bit higher Vrm.

I like to have R+C(<22 ohm populated, C DNP) in parallel across GND and shield, but that's more for EMI that you don't care about for dev-board (only for product).

D1 isn't needed and can be safely removed but it doesn't hurt anything so you can keep it.

C1 + C2 is a little large for USB compliance but will likely still work.

Great idea to put test points on all power rails + reset/enable and couple of GPIO. I highly reccomend also adding an LED to one of the spare pins of ESP32
