When you connect multiple PWM signal pins, most I/O ports of the control board will be occupied and PWM ports may then be insufficient. This SunFounder 16-channel 12-bit PCA9685 PWM Servo I2C Driver can work it out as long as your control board supports I2C communication. It only occupies two I/O ports to connect 16 channels of PWM signal. In addition, it can connect at most 62 driver boards by cascading with another I2C port and control each driver board by addressing, thus controlling up to 992 servos.
