GPIO Description
The Jetson.GPIO library for Jetson motherboards allows developers to interact with external hardware devices via 40-pin GPIO pins.
1. GPIO Numbering
The Jetson.GPIO library supports two common numbering modes: BOARD and BCM.
Note: This tutorial only demonstrates GPIO.BOARD mode.
| Mode | Numbering Method |
|---|---|
| GPIO.BOARD | Based on physical pin numbering (1-40) |
| GPIO.BCM | Based on Broadcom chip GPIO logic numbering |
2. GPIO Pins
2.1 GPIO.BOARD Mode
One-to-one correspondence between BOARD mode pins and the 40-pin pins on the motherboard:
2.2 GPIO.BCM Mode
Pin correspondence between BCM mode and the 40-pin connector on the motherboard:
3. Other Pins
AUTOMOATION-12-pin control instructions:
Short-circuiting pins 5 and 6 automatically powers on; disconnecting them requires pressing the power button to power on.
Short-circuiting pins 9 and 10 enables WOL (Wake-up on Network); disconnecting them disables WOL.
