This 16-CH. 12-bit PWM/Servo Driver-I2C-PCA9685 for Arduino-Raspberry Pi uses I2C 7-bit address between 0x60-0x80, selectable with jumpers.Terminal block for power input (or you can use the 0.1" breakouts on the side).Reverse polarity protection on the terminal block input.3 pin connectors in groups of 4 so you can plug in 16 servos at once (Servo plugs are slightly wider than 0.1" so you can only stack 4 next to each other on 0.1" header
TB6600 stepper motor driver provides maximum 4.0A output current. TB6600 comes with output sort-circuit protection, Low-Pressure shut-off, Overheating parking and over-current protection.
