What kind of power supply do I need for Arduino Nano?
If you want to supply regulated power, then a 5 Volt regulated adapter needs to feed the +5V pin (pin27) instead. The Arduino Nano can be powered via the Mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27).
What kind of battery do I need for my nano?
You can power the Nano with 3 x AA (or AAA) alkaline cells (4.5v) connected to the 5v pin. The 4.5v will also be suitable for powering a servo. And the AA (or AAA) cells will last longer than the 9v PP3 style battery.
What kind of USB adapter do I need for Jetson nano?
If you do go this route, I would strongly recommend using a powered USB hub to connect all USB peripherals. By default the Nano is probably in 10 Watt mode. If using a Micro USB adapter you should change that immediately to 5W mode. By default, the setting should persist after reboot.
How can I tell what power supply my Jetson Nano is using?
No matter which power supply option you choose, you should first familiarize yourself with a command line utility called nvpmodel. You’ll want to make sure that you have this setup properly based on your power requirements. Whenever you startup your Nano you should query it using nvpmodel to see what model you are currently using, like this:
