It operates at 5V logic but supports 3.3V microcontrollers, features a built-in clock for free-running PWM signals, and allows chaining up to 62 modules for nearly 1,000 outputs. Ideal for Arduino and Raspberry Pi projects requiring expanded PWM outputs with minimal MCU overhead. ## 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. ## 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 | | Best Sellers Rank | #24 in Desktop Barebones | | Brand | SunFounder | | Built-In Media | 1 x PCA9685 16-Channel 12-Bit PWM Servo Driver | | Compatible Devices | Devices with I2C communication support | | Connectivity Technology | I2C | | Customer Reviews | 4.5 4.5 out of 5 stars (416) | | Item Dimensions L x W x H | 5.2"L x 4.3"W x 0.8"H | | Item Weight | 0.02 Pounds | | Manufacturer | SunFounder | | Mfr Part Number | miniLCD | | Model Name | PCA9685 | | Model Number | miniLCD | | Operating System | Linux, Windows 10 IoT Core | | Processor Brand | Nuvoton or STMicroelectronics | | Processor Count | 16 | | Processor Speed | 1 KHz | | Smart Home Compatibility | Not Smart Home Compatible | | UPC | 701715367203 | | Warranty Description | 1 Year Guarantee | ## Product Details - **Brand:** SunFounder - **CPU Speed:** 1 KHz - **Connectivity Technology:** I2C - **Included Components:** 1 x PCA9685 16-Channel 12-Bit PWM Servo Driver - **Model Name:** PCA9685 ## 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.sn/products/33879493-sunfounder-pca9685-16-channel-12-bit-pwm-servo-driver-arduino](https://www.desertcart.sn/products/33879493-sunfounder-pca9685-16-channel-12-bit-pwm-servo-driver-arduino) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-15*
