JetsonNano expansion header簡述

Jetson Nano的 40pin 擴充接腳簡述

Header上方印刷說明 

Header下方印刷說明
 

Jetson NanoGPIO接腳使用3.3V level

預設所有的siganl pins都為GPIO，除了下述

pin3(DIO2)=>I2C bus1的SDA

pin5(DIO3)=>I2C bus1的SCL

pin27(DIO0)=>I2C bu0的SDA

ping28(DIO1)=>I2C bus0的SCL

pin8(DIO14)=> UART TX

pin10(DIO15)=>UART RX

L4T有提供python library，Jetson.GPIO作為控制GPIO用

此library如同RPi.GPIO。(說明存放於Jetson系統內 ， /opt/nvidia/jetson-gpio/doc/README.txt )

Jetson.GPIO (pip module)
