Does this work with any ESP32 model?

i'm starting to look into ESP32 and just wondering does this work with any ESP32 model on the market? If not, is there a list of models that this works on?

Hey !
I quickly explored the repository of esper after seeing your request. I am not a contributor or anything linked with the project but i'll try to help.
All or almost all ESP32 have built-in antennas supporting 2.4 GHz, so they can interact with wifi , but as you can see here : https://github.com/zachmorr/esper/tree/main/hardware

The developper provided a custom PCB for the project with an ETHERNET port on it to run faster on wifi, and as you may know , ESP32 don't have ETHERNET ports .
So the "model" for you to be sure that everything is working would be the esper custom PCB (with an ESP32 in it).
Hope it helped

And , i just checked further in the README , all classic ESP32 developpement boards are available fo this project like the most used one ESP32 DevkitC,
You can check in that part of the documentation https://github.com/zachmorr/esper/blob/main/software/README.md
He explains that you will just have to enter your WIFI crendentials before building the firmware !

@0Zane appreciate you taking the time to help, I've added a comment with more information below.

Hello! @banghia112 this is compatible with generic ESP32 Wi-Fi dev boards, no ethernet needed. This project isn't maintained though and was built off an older ESP-IDF, around version 4, so you may need to do some work to find a compatible ESP-IDF version.

If you are able to get that working then I'd recommend upgrading to an ESP32 ethernet board with a compatible ethernet chip, it will be much faster and more reliable compared to ethernet
