1. Setup and Configuration of Edge Devices

Raspberry Pi / Jetson Nano Installation, SSH Access, and GPIO Control

A. Operating System Installation

Raspberry Pi

• Download the Raspberry Pi OS using the Raspberry Pi Imager tool.

• Flash the OS to an SD card (16GB+ recommended).

• Enable SSH and configure Wi-Fi during flashing (optional using Imager advanced options).

• Insert SD card → Power on → Device boots with default credentials.

B. Remote Access (SSH Configuration)

On Raspberry Pi

Enable SSH:

sudo systemctl enable ssh 
sudo systemctl start ssh

Connect from your laptop:

ssh pi@<device-ip> 

To find device IP:

ifconfig

C. GPIO (General Purpose Input/Output) Control

Raspberry Pi (Python – RPi.GPIO or GPIO Zero)

Example using RPi.GPIO:

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT)

while True:
    GPIO.output(18, True)
    time.sleep(1)
    GPIO.output(18, False)
    time.sleep(1)

D. Additional Recommended Setup

• Setup VNC for GUI remote access.

• Setup Docker for deploying applications.

• Create virtual environments for Python projects.

• Use systemd services to auto-run scripts on boot.

• Configure I2C, SPI, UART interfaces as needed.

E. Typical Use Cases

• AI object detection (Jetson Nano + camera).

• IoT sensor hub (Raspberry Pi + GPIO sensors).

• Edge inference for ML models.

• Robotics and industrial automation.

• Home automation systems.
