This page contains information on methods of powering an NVIDIA Jetson Nano 2GB using a mobile power source. This is necessary as a cabled connection to a stationary power source would strongly inhibit the S1's functionalities. However, this page also contains the basic information needed in order to select a correct power supply.

Powering Nvidia Jetson

The specifications for powering an NVIDIA Jetson are as follows:

• Voltage: 5V +- 5%
• Current: 3A
• Type: USB-C

The developer kit’s total power usage is the sum of carrier board, module, and peripheral power usage. There are two software-defined power modes for the Jetson module. The power mode can be switched with the UI interface at the top right of the desktop view. The two module power modes are:

• 10W: default mode for more performance.
• 5W: suggested for less energy use.

It is also possible to define a custom power mode. Follow the tutorial on the official "NVIDIA Jetson Linux Driver Package Software Features" docs

The Jetson Nano 2GB cannot be powered via the Micro-USB connector. Furthermore, if the voltage drops below 4.25V, the system will shut down.

Previously used hardware

During the project of 2021 we used the following hardware for powering the Jetson Nano

• Portable Power Supply (INTENSO 7313550)

Voltage: 5V Current: Max 3.1A Capacitance: 20.000 mAh

*Stationary Power Supply (PSAA 15W-050L6)

Voltage: 5VDC Current: 3A Performance: 15 W
