PCA9685 16-Channel 12-Bit PWM Servo Driver

• Contain an I2C-controlled PWM driver with a built-in clock
• 12-bit resolution for each output – for servos
• Support using only two pins to control 16 free-running PWM outputs
• 3-pin connectors in groups of 4

The PCA9685 16-Channel 12-Bit PWM Servo Driver can help a lot when there are insufficient PWM output pins for the MCU in your project. The only condition is that the main control chip supports I2C communication, which means enabling the communication between the chip and PCA9685, so as to control multiple servos simultaneously.
