PWM motor and servo controller - I2C 8-channel - PCA9685 - overlay for Feather - Adafruit 2928

Overlay for theFeatherfamily of products in the form ofan 8-channelmotor and servo controller. Control is performed usingPWM(Pulse Width Modulation) signal. The controller usesI2Cbus to communicate with the main module, e.g. Arduino. It can be used, among others, in robot projects whose mission is to control up to eight separate components simultaneously.

PWM motor and servo controller - I2C 8-channel.
