From the project
74HC165 breakout board for use with Arduino or similar
This PCB provides access to the inputs of four serially connected 74HC165s. It's perfect for expanding the number of inputs available on smaller Arduinos like the Pro Micro or Nano when building flight simulator components that interact with MobiFlight.
These boards are ready to order from JLCPCB with their SMT fabrication service. You'll receive boards with all the components soldered on except for the pin headers which you add yourself.
