Consider Arduino Nano with screw terminal extension

More robust and versatile than grove connection. Few examples:

• Amazon. Cons: no additional power input
• Digikey Cons: have to mount, pros: additional DC/GND pins
• TME Pros: room for additional connectics. Seems like an excellent choice!

Another thing to consider: I would need access to GND and Vcc for each sensor + OLED, that's 4x. Possible solutions:

• Split terminals
  • cons: sensors cable have GND, Vcc and additional cables clusters-- it will be a mess to separate them to reach the splitter.
• Stripboard (eg here)
  • cons: takes more time, might become messy with a bunch of wires connected.
• custom PCB
  • pros: clean solution
  • cons: takes even more time
