Power supply considerations for Jetson Nano Developer Kit

[linuxdev]

5V chargers on a 5V dev kit won’t damage a Nano (other non-Nano model dev kits require other voltages, all of which are higher than 5V). For the most part a 5V phone charger with 4A available should work well, and definitely won’t damage the unit. However, unless the regulation is sufficiently tight, you might find the unit shuts down when there is a very short spike in needed current…some cheap regulators can’t keep up with short power spikes and let the voltage drop for a tiny amount of time, and the Nano requires good quality regulation. Give it a try, and it won’t hurt on a Nano dev kit, but you also need to verify that it is stable under various loads. Chances are it will work. If not, then adding capacitance right at the connector would do the job (of course you’d have to create an adapter to go from cell charger to capacitor and then to the Nano).
