## Overview

The SunFounder PCA9685 is a 16-channel, 12-bit PWM servo driver featuring an I2C-controlled built-in clock that enables free-running PWM outputs. Compatible with 3.3V and 5V microcontrollers, it supports chaining up to 62 boards for controlling up to 992 servos or LEDs. Ideal for complex robotics and LED projects, it offers precise 4µs resolution at 60Hz, freeing your MCU from continuous signal management.

## Description

Introduction PCA9685 16-Channel 12-Bit PWM Servo Driver can help a lot when there are insufficient PWM output pins for the MCU in your project. The only condition is that the main control chip supports I2C communication, which means enabling the communication between the chip and PCA9685, so as to control multiple servos simultaneously. Component List - 1 x PCA9685 16-Channel 12-Bit PWM Servo Driver More informations, please refer to http://wiki.sunfounder.cc/index.php?title=PCA9685_16_Channel_12_Bit_PWM_Servo_Driver Suitable for 14 years or above.

Review: Easy to program - I liked this servo controller because their software was easy to download and install. It programmed well, but unfortunately caught fire when used with a robot arm. However, I am not sure if it was receiving less power than it needed. It would have been nice if the manufacturer had put instruction guide which listed power requirements. This controller could handle up to 16 servos, but you need to know how much power to give it per servo. I liked the controller, just wish it had not caught fire. Fortunately, it only damaged the controller, but smelled up the house.
Review: 2nd review, still 5 star - With the 2 PCBs that I purchased, I can now drive 64 Servos total. Yes, 64 Servos. Your PCBs control 32 of these servos... ZERO issues. Excellent product. I would say I'd buy again... but I don't even have 64 servos yet !!!!! If I ever buy more than 64 servos, I'll buy these again to drive them, no question. These PCBs work fantastic. Thanks.

## 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

### ⭐⭐⭐⭐⭐ Works just fine Arduino UNO and MEGA
*by J***G on October 7, 2015*

I bought two of these things to go with my Arduino MEGA and also an UNO. The Arduino(s) drive this board, and then I used the PWM outputs to drive logic level MOSFETS which in turn control 12V 1-amp LEDs. You can get the PCA9685 library from AdaFruit that Arduino uses to control the board. Everything works great! I've got LEDs all over the place and am worried that I might be starting to hallucinate from all of the flashing and strobing. :(
