## Overview

The SunFounder PCA9685 is a powerful 16-channel PWM servo driver designed for Arduino and Raspberry Pi, featuring I2C control, 12-bit resolution, and the ability to chain multiple units for extensive output capabilities. Perfect for hobbyists and professionals alike, it simplifies complex projects while providing precise control over multiple servos and LEDs.

## Description

SunFounder PCA9685 16 Channel 12 bit PWM Servo Driver for Arduino and Raspberry Pi

## Features

- Contain an I2C-controlled PWM driver with a built-in clock. It means, unlike the TLC5940 family, you do not need to continuously send it signals tying up your microcontroller; it's completely free running
- 5V compliant, which means you can control it from a 3.3V microcontroller (this is good when you want to control white or blue LEDs with 3.4+ forward voltages)
- Support using only two pins to control 16 free-running PWM outputs – you can even chain up 62 breakouts to control up to 992 PWM outputs
- 3 pin connectors in groups of 4, so you can plug in 16 servos at one time (Servo plugs are slightly wider than 0.1" so you can only stack 4 next to each other on 0.1" header
- 12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate
