Compatible with popular platforms like Arduino and Raspberry Pi, it supports chaining up to 62 boards for nearly 1,000 outputs, making it a powerhouse for complex robotics and lighting projects. ## Description Product description Introduction The PCA9685 is a 16-channel I2C-bus controlled LED controller optimized for Red/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has individual 12-bit resolution (4096 steps) PWM controller with a fixed frequency. The controller operates at a programmable frequency from a typical 24 Hz to 1526 Hz with a duty cycle that is adjustable from 0% to 100% so the LED can be set to output a specific brightness. All outputs are set to the same PWM frequency. With the PCA9685 as the master chip, the 16-channel 12-bit PWM Servo Driver only needs 2 pins to control 16 servos, thus greatly reducing the occupant I/Os. 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. Moreover, it can be connected to 62 driver boards at most in a cascade way, which means it will be able to control 992 servos in total.

Thanks. Review: Worked for Droid Division K2SO - Worked perfect.. Used to control servos in a Droid Division 3d Printed K2SO to contol the LED eyes movement. ## Features - Contains 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 and still safely drive up to 6V outputs, which is good when you want to control white or blue LEDs with a 3.4V+ forward voltage - Supports 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 4 groups, so you can plug in 16 servos at one time (Servo plugs are slightly wider than 0.1" so you can only stack 4 adjacent ones on 0.1"-hole female headers. - 12-bit resolution for each output - for servos, that means about 4us resolution at an update rate of 60Hz. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07WS5XY63 | | Best Sellers Rank | #25,152 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #2 in Motor Drives | | Brand | AITRIP | | Compatible Devices | Raspberry Pi, Arduino | | Connectivity Technology | I2C | | Customer Reviews | 4.5 out of 5 stars 121 Reviews | | Manufacturer | AiTrip | | Model Name | PCA9685 | | Operating System | Linux | | UPC | 701715429840 | | Wireless Communication Standard | Bluetooth | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** AITRIP - **Connectivity Technology:** I2C - **Model Name:** PCA9685 - **Operating System:** Linux - **Wireless Communication Standard:** Bluetooth ## Images ![PCA9685 16 CH 12Bit PWM Servo Motor Driver Board Controller IIC Interface for Arduino Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+ and Robot (2pcs) - Image 1](https://m.media-amazon.com/images/I/61FGGDyCN9L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ As described *by B***B on May 7, 2026* What I ordered.
