Arduino 3.x

Arduino 3.x is not officially suported by PlatformIO - see platformio/platform-espressif32#1225

Due to the lack of further development of the Espressif 32 Arduino Core for PlatformIO, the pioarduino fork was created.

Arduino 3.1.x

platform-espressif32	Arduino Core	based on ESP-IDF	platformio.ini

class PCA9685:
    """
    This class provides an interface to the I2C PCA9685 PWM chip.
    The chip provides 16 PWM channels.
    All channels use the same frequency which may be set in the
    range 24 to 1526 Hz.
    If used to drive servos the frequency should normally be set
