W5500 Communication issues

Hi, I'm trying to add a W5500 on my custom ESP32 board and I am getting weird issues. Before talking about it here is the schematics: https://puu.sh/IHzpd/069d50d665.png https://puu.sh/IHzpt/3e91e1b600.png With the regular Ethernet library it doesn't seem to be able to pick up that this is the W5500...

Re: ESP32-WROOM-32D dev board upload over UART

I'm seeing the regular serial printout when the TX/RX is connected, when the program already on there is running. The TTL has common ground with the ESP32. I noticed when I tried to flash over USB if anything is connected into the RX GPIO(this time a LoRa reciever), the Boot button (on the devkit, n...

I've been trying to program an ESP32D with an CH340G TTL converter, and I can read the serial print out fine, but when I'm trying to upload with my current setup on the development board, I can't connect. The buttons added in the schematic works fine when plugged into USB, but not whenever running d...

ESP32-01s SHT3x libraries

I got a SHT3x and it works fine on a regular ESP32 wroomer board, but getting it to run with an ESP32-01s have been unsuccessful. Can't really find anything specifically for ESP32 in general for the SHT3x and was wondering if it might just not be possible on the ESO32-01s?

5V Dip switch

So I'm trying to get some inputs to my ESP32 WROOM 32 for testing, and I have some 5V dip switches here and was wondering how this design bellow would faire if 5V is supplied on the dip switch and board. Would this be alright, for input testing in general, not prolonged used. https://puu.sh/HWuIT/48...
