Let's learn how to set up ROS on a GPU-based SBC—Jetson Nano. This is going to be straightforward since we're going to set up Nano with Ubuntu. Follow these steps:

1. To install the OS, follow these steps:
   1. Download the OS image file from this link: https://developer.nvidia.com/jetson-nano-sd-card-image-r322.
   2. Once the image is downloaded, insert the SD card into your system and open Etcher.
   3. Select the downloaded image and the specific SD card location and click Flash!.
2. To load the OS, make sure that the SD card is loaded. Power the SBC using an appropriate power supply adapter. If everything is successful, you should see the following output:

3. Installing ROS is pretty straightforward, as we saw in the Installing ROS on the Tinkerbord Armbian OS section. Follow the same steps mentioned in that section.

Let's now learn to control GPIOS from ROS.
