Review: I have an Arduino project that requires six servos. This 16 channle servo driver is amazing. It worked flawlessly out of the box. My difficulty was that the driver uses I2C communications and that made it difficult to use the Arduino as a master since my I2C network has the Arduino as a slave. And it then became a tradeoff of using six of the Arduino outputs to drive the servos direcly, or continue with a modified I2C network and have ten channels not used. It would be nice to have this product available in an eight channel version. But, as designed, this is an amazing product. Highly recommended. ## Features - Communication Interface: IIC - 16-way steering gear control - Voltage: DC5-10V power supply - The PCA9685 chip is wrapped in the center of the board - All PWM output lines have a 220 ohm series resistor protection and can easily drive LED. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07BRS249H | | ASIN | B07BRS249H | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #4,245 in Computers ( See Top 100 in Computers ) #24 in Single-Board Computers | | Color | Blue | | Customer Reviews | 4.5 4.5 out of 5 stars (293) | | Customer reviews | 4.5 4.5 out of 5 stars (293) | | Date First Available | 24 May 2018 | | Date First Available | 24 May 2018 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 26 g | | Item model number | 3-01-1070-2pcs | | Item model number | 3-01-1070-2pcs | | Manufacturer | HiLetgo | | Manufacturer | HiLetgo | | Package Dimensions | 12.2 x 8.3 x 2.3 cm; 26 g | | Package Dimensions | 12.2 x 8.3 x 2.3 cm; 26 g | | Part number | 3-01-1070-2pcs | | Size | Small | ## Images ![2pcs PCA9685 16 Channel 12-Bit PWM Servo Motor Driver IIC Module for Arduino Robot - Image 1](https://m.media-amazon.com/images/I/61JtDt-gT7L.jpg) ## Questions & Answers **Q: What library do you need for the Arduino to control this? Any sample code?** A: Limor Fried wrote a lib and posted it to github: https://github.com/adafruit/Adafruit-PWM-Servo-Driver-Library **Q: What I2C address does this use? 0x40 like the Adafruit version?** A: Yes. **Q: V+ at the terminal block is not directly connected to V+ on the rest of the board. How do I get actual power to the servos?** A: No the V+ of terminal block goes through a tiny transistor but since it does not turn on, you would have to mod the board to get power to servos from that terminal. Others just input to the pin near VCC labled V+ **Q: What are the peak amps for this board?** A: Each of the 16 outputs is limited to about 25mA. That would make the total current capability of the board no more than 400mA. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by H***H on 8 January 2026* Works great, easy to program. ### ⭐⭐⭐⭐⭐ Review *by D***E on 8 May 2024* I have an Arduino project that requires six servos.

My difficulty was that the driver uses I2C communications and that made it difficult to use the Arduino as a master since my I2C network has the Arduino as a slave.

Highly recommended. ### ⭐⭐⭐⭐⭐ Review *by A***E on 11 September 2018* These are cool motor drivers; they're built with fairly decent quality. You can control anything with a PWM input too, like LEDs. You can also cascade these to control over 900 servos, lol! However, some of the pins came bent; probably got bent out of shape during shipping, although reshaping them isn't too tricky with needle nose pliers, and they function. I have 2 6v servos controlled through a PCA9685 using a Arduino Uno R3 as a platform for controlling the servos with 2 10k potentiometers. Pretty neat, although there is zero documentation that come with these, so unless you've already got some information about using these you might be in a situation where you'll need to do research to supplement the lack of documentation. Luckily the Arduino community provides essential hidden knowledge to the public regarding electronics, usually free of charge, and helps to demystify these useful electronic modules. I can't imagine why a manufacturer wouldn't want an informed public to know of the usefulness of the product they're producing, which is to be sold, but these aren't too hard to work with, and looking into how to do interesting things with these isn't too tough either with all the open source projects out there that call for using these. ## Frequently Bought Together - HiLetgo 2pcs PCA9685 16 Channel 12-Bit PWM Servo Motor Driver IIC Module for Arduino Robot - Deegoo [4-Pack] MG996R 55g Metal Gear Torque Digital Servo Motor for Futaba JR RC Helicopter Car Boat Robot - Beffkkip 4Pcs SG90 9g Micro Servos for RC Robot Helicopter Airplane Controls Car Boat --- ## 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.vn/products/256334322-2pcs-pca9685-16-channel-12-bit-pwm-servo-motor-driver](https://www.desertcart.vn/products/256334322-2pcs-pca9685-16-channel-12-bit-pwm-servo-motor-driver) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-23*
