Hi,

I'm relatively new to PCB design and I just finished my first board with the ESP32. It uses a USB C 6 pin, an ESP32 PICO MINI 02 N8R2, and 6 buttons with an SD card reader, a 4 pin header for an OLED display, and a 2 pin header for UART.

The stackup is as follows:

Top - Components, small voltage plane

L1 - GND

L2 - 3.3V

Bottom - signals for SD card reader

I just wanted to know if there was anything I could improve on, or if there were any fatal errors that would prevent it from working, I'd be grateful for any feedback. Thanks!
