原理分析：

Jetson Nano控制SIM7020 开关机_引脚

import Jetson.GPIO as GPIO
import time

pwr_pin = 7
GPIO.setmode(GPIO.BOARD)
GPIO.setup(pwr_pin, GPIO.OUT)
pwr_pin = 7
GPIO.setmode(GPIO.BOARD)
GPIO.setup(pwr_pin, GPIO.OUT)


try:


        print("switch")
        GPIO.output(pwr_pin, GPIO.HIGH)
        time.sleep(2)
#        print("off")
        GPIO.output(pwr_pin, GPIO.LOW)
#        time.sleep(2)

except KeyboardInterrupt:
    GPIO.output(pwr_pin, GPIO.LOW)
    GPIO.cleanup()
print("done")

运行程序，拉高7引脚两秒，改变开关机状态：

sudo python3 pwr.py
