Compatible with both 5V and 3.3V systems, it supports chaining up to 62 boards for nearly 1,000 outputs, making it ideal for complex robotics and LED projects. ## 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B014KTSMLA | | Brand | SunFounder | | Computer Memory Type | EPROM | | Customer Reviews | 4.4 4.4 out of 5 stars (413) | | Date First Available | August 28, 2015 | | Hardware Platform | Arduino | | Is Discontinued By Manufacturer | No | | Item Dimensions LxWxH | 5.2 x 4.3 x 0.8 inches | | Item Weight | 0.32 ounces | | Item model number | miniLCD | | Manufacturer | SunFounder | | Number of Processors | 16 | | Operating System | Linux, Windows 10 IoT Core | | Processor | 1 KHz 210 | | Processor Brand | Nuvoton or STMicroelectronics | | Product Dimensions | 5.2 x 4.3 x 0.8 inches | | Series | PCA9685 | ## Product Details - **Brand:** SunFounder - **Model name:** PCA9685 16 Channel 12 bit PWM Servo Driver - **CPU model:** 210 - **Connectivity technology:** I2C - **Included components:** 1 x PCA9685 16-Channel 12-Bit PWM Servo Driver ## Images ![SunFounder PCA9685 16 Channel 12 bit PWM Servo Driver for Arduino and Raspberry Pi - Image 1](https://m.media-amazon.com/images/I/61W+eG+LigL.jpg) ## Frequently Bought Together - SunFounder PCA9685 16 Channel 12 bit PWM Servo Driver for Arduino and Raspberry Pi - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - Arduino Uno REV3 [A000066] --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/268119272-sunfounder-pca9685-16-channel-12-bit-pwm-servo-driver-arduino](https://www.desertcart.us/products/268119272-sunfounder-pca9685-16-channel-12-bit-pwm-servo-driver-arduino) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-17*
