ESp32 - Lan8720 schematic review

[remco.halman]

Hello all,

Thank you for reading this post. What im struggling with is the not so much docs/examples to find of a ESP32-WROOM-32UE-N16 in combination of a SD slot and a Lan8720. This board is meant to be remotely placed in a Escaperoom and using MQTT for the communication and no WiFi therefor the Lan connection. The SD slot is used for loging/firmware update/configuration files.

Attached is the schematic if you would have the time would and could you give some tips on where to proceed?

The schematic is not complete yet. I am adding a CH340 for programming and going to add 4 relays and 6 inputs via optocouplers and transistors etc.

Thank you in advance
