## Overview

The KEYESTUDIO 16-Channel 12-bit Servo Motor Driver Board is a compact, stackable expansion designed for Arduino R3 controllers. Featuring an I2C interface, it enables simultaneous control of up to 16 servos with high 12-bit PWM resolution. Its independent 6V power input ensures stable servo operation, while the double-sided PCB holes facilitate easy prototyping and soldering. Ideal for advanced robotics projects, it comes with comprehensive online tutorials to streamline your build.

## Description

Specification 1.I2C input, to control 16-channel PWM output 2.Servo power supply independent V + input up to 6V 3.Logic signal and logic power independent output 3-5v 4.Frequency of 40-1000Hz 5.Number of channels: 16-channel 6.Resolution: 12-bit

Review: Not for the faint of heart - I got this for a robotic arm project that I am working on and it works well. It makes connecting many servos to a microcontroller much easier. It uses the IIC protocol for communications so it is a bit different to code for when you are used to coding and wiring each individual servo to the microcontroller itself, but once you get one servo working, the rest is a breeze. I would definitely recommend this item for more advanced projects. It saves a bunch of time and hassle in the long run.
Review: Cheap but works - Awesome thank you

Awesome thank you

### ⭐⭐⭐⭐ Good but not much information online about it.
*by B***T on December 3, 2025*

A little bit of a learning curve, but once you get used to the library then it works fine. Not very clear which library should be used so I had to do some extra research to find out that the adafruit library was the right one.
