Adafruit 16-Channel 12-Bit PWM / Servo Driver, I2C, PCA9685 The Adafruit 16-channel 12-bit PWM / servo driver board enables the control of up to 16 servos / LEDs with only two I2C pins (SCL & SDA). Theoretically, 62 breakout boards can be operated on one microcontroller, which enables up to 992 PWM outputs. The board has a PWM driver with integrated clocking. This means that a signal from the microcontroller does not have to be continuously present and it is not blocked as a result. 6 address-select pins allow up to 62 boards on one Arduino. The board is delivered assembled and tested. The pin headers and the terminal block are not soldered on! Further useful information, code examples for CircuitPython & Arduino and tutorials can be found in the Adafruit Learning System: https://learn.ad.

You want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. You could give up OR you could just get this handy PWM and Servo driver breakout.
