Engineering & Architecture Engineering (Mechanical / Chemical / Civil / Electrical)

For my product I need a PCB designed so I can let produce it in PCB format. 

Currently the motorunit is made with a: 

- 12/24v stepdown converter to USB/5V

- 3V relais board

- ESP32 38pin connectorboard

- 4 chanel 817 optocoupler board 

- 7 external pullup resistors of 4k7

- 3 external pushbuttons, input esp32 to GND (screw terminal)


I would like to combine these components in one PCB. 


Therefore I would like to connect 12 or 24V to the input side of the PCB

The 3V relaisboard must be triggered with the ESP32, NO/COM/NC must be available in screw terminals
VCC (3,3v), GND, port 21 and 22 of the esp32 need to be available as screw terminal for my I2C oled display

Optocouplers must be connected between GND and individual input of ESP32 via pullup of 4k7

a screwterminal must be available for pushbuttons, GND and 3 inputs with pullup of 4k7


I am an electrical engineer but no experience with PCB, so you can ask me anything. 

Please let me know your thoughts and price.

Kind regard, 

Rob
