This 16 Channel PWM Servo and 16 GPIO board can connect to 16 servo motors and the 16 input/output GPIO channels can be customised to your own preferences. 


Features

  • 2P Terminal Block: 5V input for the PWM (V+) & GPIO output (Pin 10 V+)
  • Two i2c device connectors:
    • J20: GND, +5V, SDA, SCL (with a level converter, safe for 5V devices)
    • J21: GND, 3V3, SDA, SCL

  • 8 of the GPIO channels can directly connect to 2 stepper motors

Specification
  • The PCA9685 is an I2C-bus-controlled 16-channel LED controller optimized for LCD Red/Green/Blue/Amber (RGBA) colour backlighting applications. Each LED output has its own 12-bit resolution (4096 steps) fixed frequency individual PWM controller that operates at a programmable frequency from a typical of 40 Hz to 1000 Hz with a duty cycle that is adjustable from 0% to 100% to allow the LED to be set to a specific brightness value. All outputs are set to the same PWM frequency.
  • PCA9685 also has a built-in oscillator for the PWM control. However, the frequency used for PWM control in the PCA9685 is adjustable from about 40 Hz to 1000 Hz as compared to the typical 97.6 kHz frequency of the PCA9635. This allows the use of PCA9685 with external power supply controllers. All bits are set at the same frequency. The PCA9685 has 4096 steps (12-bit PWM).
