    1) Do a visual inspection:
    - Check solder connection
    - Check component orientation
    - Check correct components mounted (especially the power regulators)
    2) Slowly apply power.
    - Keep the current limit low.
    - Gently increase voltage in steps.
    - Check voltage regulator(s) output(s). Check from low voltage to higher. I.e. 3.3V regulator, pause at 3.5V, check output (<= 3.3V).
    - Keep an eye on current consumption. Increase if needed.
    3) Check for components getting hot.

    4) Optional: watch this video https://www.youtube.com/watch?v=fEQyW0qQFjk (First power of device!)

    5) Program software
    6) Check functionality
