PCA9685 16 Channel 12 Bit Servo Motor Driver
This is the PCA9685 16 Channel 12 Bit Servo Motor Driver, With just two pins, you can control 16 free-running PWM outputs. Do you want to build a robot or a hexapod walker? Perhaps you're creating a work of art with many moving parts, or you need to drive a large number of LEDs with precise PWM output. Your microcontroller has a limited number of PWM outputs, and you're almost out! Do you require more than 16 PWM outputs? No worries. Chain up to 62 of these beauties together for a total of 992 PWM outputs.
This is an I2C-controlled PWM driver with an integrated clock. That means you don't have to send it to signal all the time, tying up your microcontroller; it's completely free to run! It is 5V compliant, which means it can be controlled by a 3.3V microcontroller while driving up to 6V outputs safely. This is useful when controlling white or blue LEDs with forward voltages of 3.4 or higher. There are six address select pins, allowing you to connect up to 62 of these to a single I2C bus for a total of 992 outputs.
If you want to control the servo motors with this 16-channel servo motor driver, for that you will need a few essential components like
Features:
- Adjustable frequency PWM up to about 1.6 KHz
- Configurable push-pull or an open-drain output
- The output enable pin to quickly disable all the outputs
- Reverse polarity protection on the terminal block input
- 3 pin connectors in groups of 4 so you can plug in 16 servos at once
- Terminal block for power input
Also check the 16-Channel 12-bit PWM/Servo Driver Shield for Arduino offered by Robocraze. The shield is designed for development boards compatible with Arduino and allows the control of up to 16 servos over I2C with only 2 pins. It features an onboard PWM controller that can drive all 16 channels simultaneously with no additional processing overhead on the Arduino
