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 | #22,772 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 | 4.6 4.6 out of 5 stars (117) | | Manufacturer | AiTrip | | Model Name | PCA9685 | | Operating System | Linux | | UPC | 701715429840 | | 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) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - 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) - Smraza 10 Pcs SG90 9G Micro Servo Metal Geared Motor Kit for RC Robot Arm/Hand/Control with Cable, Mini Servos for Arduino Project (10) - 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 --- ## 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.vu/products/164346623-pca9685-16-ch-12bit-pwm-servo-motor-driver-board-controller](https://www.desertcart.vu/products/164346623-pca9685-16-ch-12bit-pwm-servo-motor-driver-board-controller) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
