Designed for efficient microcontroller use, it offers smooth servo control and LED dimming with cross-voltage compatibility, making it a versatile choice for advanced robotics and lighting projects. ## Description Specification: Frequency: 40 - 1000Hz Channel Number: 16 Channel Resolution: 12 Bit Voltage: DC 5 - 10V "Classic" Pin Mode Connection: - +5V: VCC - GND: GND - Analog 4: SDA - Analog 5: SCL Connection with MEGA Pins: - +5V: VCC - GND: GND - Digital 20: SDA - Digital 21: SCL Connection with Other Boards: - +5V: VCC - GND: GND - SDA: SDA - SCL: SCL Note: - The VCC pin only supplies power to the chip. If you want to connect a steering gear or LED lights, use the V+ pin to supply power. The V+ pin supports a power supply of 3.3 - 6V (Chip Safe Voltage: 5V). We recommend to use an external power supply through the power terminal. Features: - This one uses i2c communication, built-in PWM drive and a clock. This means that it will be very different from the TLC5940 series. You don't need to keep sending signals to occupy your microcontroller. - It's 5V compatible, which means you can also control it with a 3.3V MCU and drive it safely to a 6V output (3.4+ positive voltage is fine when you want to control a white or blue indicator). - 6 Address selection pins allow you to attach 62 driver boards to a single i2c bus for a total of 992 PWM outputs. That would be a huge resource. - About 1.6Khz adjustable PWM output. - For the stepper motor, the output is prepared at 12 bit resolution, which means that the update rate at 60Hz is able to achieve 4us resolution. - Configurable push pull output or open circuit output. - Output enable pin can quickly disable all outputs. - Green Power indicator. - You can insert 16 servo motors at a time in 4 sets of 3-pin connectors (servo motor plugs are slightly wider than 0.1, so you can fit 4 pairs of 0.1 connectors). - Reverse polarity protection of input on junction board. - A large capacitor is placed on the V+ line (which you will need in some cases). The maximum voltage of the ## Features - Using I2C communication, built in PWM driver and a clock. This means that it will be very different from the TLC5940 series. You don't need to keep sending signals to occupy your microcontroller. - PCA9685 IIC module 5V compliant, which means you can also control it with a 3.3V MCU and drive it safely to a 6V output, which is good when you want to control white or blue LEDs with a 3.4V+ forward voltage. - 6 Address select pins so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs. - PCA9685 module 2-bit resolution for each output - for servos, that means about 4us resolution at an update rate of 60Hz. - 16 Channel PWM/Servo Driver IIC interface-PCA9685 for arduino or Raspberry pi shield module servo shield. ## Technical Specifications | Specification | Value | |---------------|-------| | RAM | DDR3 | | Brand | DiGiYes | | Series | DiGiYes | | Operating System | Linux | | Item Weight | 0.317 ounces | | Product Dimensions | 2.75 x 0.98 x 0.39 inches | | Item Dimensions LxWxH | 2.75 x 0.98 x 0.39 inches | | Processor Brand | Broadcom or Atmel (Microchip) | | Number of Processors | 1 | | Manufacturer | DiGiYes | | ASIN | B0BKG7QSSR | | Date First Available | October 25, 2022 | ## Product Details - **Brand:** DiGiYes - **Model Name:** DiGiYes - **Connectivity Technology:** I2C - **Included Components:** PWM driver - **Operating System:** Linux ## Images ![PCA9685 16 Channel PWM Servo Motor Driver 12-Bit IIC Module for Arduino Robot or Raspberry pi - Image 1](https://m.media-amazon.com/images/I/71mJuSIlKJL.jpg) ![PCA9685 16 Channel PWM Servo Motor Driver 12-Bit IIC Module for Arduino Robot or Raspberry pi - Image 2](https://m.media-amazon.com/images/I/71EVWAuTdpL.jpg) ![PCA9685 16 Channel PWM Servo Motor Driver 12-Bit IIC Module for Arduino Robot or Raspberry pi - Image 3](https://m.media-amazon.com/images/I/81namAJM+cL.jpg) ![PCA9685 16 Channel PWM Servo Motor Driver 12-Bit IIC Module for Arduino Robot or Raspberry pi - Image 4](https://m.media-amazon.com/images/I/71JtsmvjDPL.jpg) ![PCA9685 16 Channel PWM Servo Motor Driver 12-Bit IIC Module for Arduino Robot or Raspberry pi - Image 5](https://m.media-amazon.com/images/I/71SbrSpcaCL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Servos for Miles! *by A***R on November 6, 2024* The media could not be loaded. Paired with a RPI4b and a little help from AI, you have the coolest animatronic you can make. Super easy to wire and control from code. ### ⭐⭐⭐⭐⭐ Works *by D***O on May 3, 2023* So far I have four servo motors running. Probably great some more servos..build to robot. ### ⭐⭐⭐⭐ Seems well made *by G***E on February 27, 2024* This seems like a nice piece of kit.All of the production looks good aside from some film on the back, but that's only cosmetic.Solder lugs, and installed pins all look good.I look forward to using this in a future product. --- ## 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/502100201-pca9685-16-channel-pwm-servo-motor-driver-12-bit-iic](https://www.desertcart.vn/products/502100201-pca9685-16-channel-pwm-servo-motor-driver-12-bit-iic) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-18*
