Stress Testing

Now that you have chosen your power supply and connector, make sure to test your project out and observe its behavior. Depending on the manufacturer, power supplies may have varying performances. Make sure to test the wall adapter over a certain period of time to ensure that the microcontroller won't brownout, and power supply won't reset under a load. For certain projects using capacitive touch sensors, make sure to test to see if there are any latencies caused by noisy power supplies.

If you are powering your project remotely, make sure to always test it with the battery. Batteries can provide varying outputs depending on the load attached and battery chemistry. This can also cause the microcontroller to brownout or stop providing power.
