Adafruit PCA9685 servo controller to control a L298N H-Bridge

With this two Python programs and the Adafruit PCA9685 Python library it is possible to use a PCA9685 servo controller to control a L298N H-Bridge. Due to the fact that the Raspberry Pi has problems to generate a clear PWM signal I am using the PCA9685 servo controller to generate the PWM signal for the L298N H-Bridge to set the spinning speed.

The PCA9685 servo controller board is connected via the I2C bus to a Raspberry Pi.

The picture below shows my setup:
