Servo Hat Jetson Nano

Hi! I have a question about Servo on Jetson Nano. I connect the servo controller like at first picture. Then I use the command sudo i2cdetect -y -r 1 to check the pins and see the 40 and 70 address (third picture). Then I run the simple code to control servo:

import Jetson.GPIO as GPIO
from adafruit_servokit import ServoKit

kit = ServoKit(channels=16)

kit.servo[0].angle = 90

But the servo doesn’t move and the 70 address disappears (second picture). How can I solve this problem?



Please check if can gain some ideas from Jetson Nano wiring to PWM driver for servo control. - #2 by jaybdub
