You’ll find PDF schematics and Arduino client/server samples on Github. Note they had to modify the Ethernet library for Arduino for the Web server sample, so you’d have to copy libdeps directory from Github into the libraries directory of your Arduino IDE installation.

ESP32 T-Lite board is sold for $9.43 on Aliexpress with unsoldered female headers, and you’d need to add an extra $4.93 to get the Ethernet expansion board.
