Electronic and Hardware Setup for GPIO and Seven Segment Display

GPIO

This Readme talks about basic electronic setup for LED on Jetson Nano

GPIO Hardware

• 1 Qty 5mm red LED
• 1 Qty P2N2222 Transistor
• 1 Qty 330Ω resistor
• 1 Qty 10kΩ resistor
• Hookup wire
• Breakboard

GPIO Setup

GPIO Electronic Wiring

The Collector, Base, and Emitter are different depending on which part number you have. We’re using a P2N2222 here. We will be wiring the red wire to +5V on Pin 2 on the Jetson, the black wire to GND on pin 6, and the transistor Base through the base resistor on Pin 12.

GPIO Result

Seven Segment Display

Seven Segment Display Hardware

• 1 Qty 4 Character 7 Segment LED made by Adafruit
• Hookup wire
• Breakboard

Seven Segment Electronic Wiring

• GND J3A1-14 -> LED Backpack (GND)
• VCC J3A1-1 -> LED Backpack (VCC – 5V)
• SCL J3A1-18 -> LED Backpack (SCL)
• SDA J3A1-20 -> LED Backpack (SDA)
