I need a pcb which consists of esp32 and PCF8575 and couple of screw terminals.

Let’s clarify your design requirements. I have 2 questions to get started. First question:
  1. Which ESP32 variant would you like to use? For example, would you prefer ESP32-WROOM-32 or ESP32-C3?

Great. For the I/O expander, would you like to use the standard PCF8575 part? Also, please let me know how many screw terminal blocks you need (e.g., 2 blocks for power and I/O, or another number)?
Confirm PCF8575 usage
