  Program the Pi 4

  Download your flavor of pi os, personally I'm using Ubuntu 22.04 because ROS2 Humble Hawksbill is supposedly the most stable on it

  I would use Pi flasher so you can modify the values for login and WiFi

  Then plug in that SD card and flash that Pi

  Mount motor hat

  There's many flavours of motor hats but this one is mine or at least the one I found cheapest on Amazon

  I would not use the bottom mount points and use smaller ones so something like this would work with the M.2 screws that come with the SunFounder Pi Hat
