Servo2 Module

SERVO 2 is an updated servo driver module in the M5Stack stackable module series. It uses a PCA9685 16 channel PWM controller to control 16 channel servos at the same time. The power input is 6-12V DC and two SY8368AQQC chips are used for voltage reduction.

Support the following products:

Micropython Example:

import os, sys, io
import M5
from M5 import *
from module import Servo2Module
servo = Servo2Module()
servo.position(0, degrees=90)
servo.release()
