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!
