Servo Driver PCA9685 PWM I2C 16 Channel 12 bit

৳475
The PCA9685 Servo Driver is a powerful 16-channel PWM controller that allows for precise control of multiple servos with 12-bit resolution via an I2C interface. It’s perfect for robotic arms, multi-leg robots, and large automation systems where controlling many servos at once is required. The I2C communication simplifies wiring, allowing you to control all 16 channels with just two wires, making it ideal for space-constrained projects. Popular in Bangladesh among robotics teams, makers, and students, this driver module provides smooth, reliable servo control for both hobbyist and professional applications.

The PCA9685 Servo Controller is an I²C-based module that provides 16-channel, 12-bit PWM output, ideal for controlling multiple servos or LEDs with high precision. Commonly used in robotics, drones, and automation projects.

This board features PCA9685. With this you can control 16 servos simulteneously.

Features:

  • It's an i2c-controlled PWM driver with a built in clock. 
  • It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages)
  • 6 address select pins so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs - that's a lot of servos or LEDs
  • Adjustable frequency PWM up to about 1.6 KHz
  • 12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate
  • Configurable push-pull or open-drain output
  • Output enable pin to quickly disable all the outputs

The board comes with-

  • Terminal block for power input (or you can use the 0.1" breakouts on the side)
  • Green power LED
  • 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
  • A spot to place a big capacitor on the V+ line (in case you need it)
  • 220 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial
  • Solder jumpers for the 6 address select pins
