Review on Waveshare Power Supply Applicable Jetson by Ben Rodriguez

My EE colleague warned me that many barrel connector Revain power supplies have an outside diameter of 5.5mm and an inside diameter of 2.5mm and although they can make connections with the right power, they are unreliable and cause problems, especially if your JetsonNano is in a shock and vibration environment (e.g. a robot). The JetsonNano requires a barrel with 55mm OD and 2.1mm ID for a solid connection. This power supply does just that and works great.
