quick and effective way to control servos

Reviewed in the United States on February 3, 2019

Verified Purchase

With a project coming up that requires 18 servos using a nano controller, I ordered this unit. I have only used it single so I do not know how well it works chained but single operation has been excellent. I tested with 6 servos on the various outputs and the results were excellent. Code was easy with the available libraries and the control was easy to set up. I could not see a visible lag in the controls.
Well made and easy to use, I recommend it if you have more than 2 servos to control. Plus shifting the power to the servo onto the unit saves the controller from being overtaxed.

Works well for raspberry pi project

Reviewed in the United States on February 9, 2020

Verified Purchase

I have a raspberry pi connected to a robotic arm made of servo motors and this works well for controlling all of them. The pi cant really handle multiple PWM signals at once so this was needed.

Control up to 16 servos from a single board!

The media could not be loaded.

I had no problems setting this up using the Adafruit_PWMServoDriver library. Follow the Adafruit tutorial and you’ll have this up and running in no time. In my uploaded video I used an Arduino Nano compatible board and connected pin A4 for SDA and pin A5 for SCL using the Adafruit library. I had more problems with the cheap servos I bought than I did with the driver board but all 16 channels work just fine. Great product and easy to use.

Works but may not be suitable for RGB LEDs

Reviewed in the United States on April 18, 2017

Verified Purchase

The headers were soldered by some sloppy/rushed/underpaid worker so they're not straight but they work.
Contrary to my expectations, it's not suitable to drive rgb leds because the pwm pulses are happening on the cathode (GND) side instead of the anode or (VCC) side, but rgb leds typically share a common cathode.
Maybe I missed something but there's not too many ways to hook this up and the pwm row definitely acts as a sink.

Faulty / Broken Trace

Reviewed in the United States on October 10, 2021

Verified Purchase

The large V+ connector does not work as there seems to be a broken trace in the board. There are two other V+ connection points but they are too small for wires that are rated for the required Amps.

Reviewed in the United States on July 5, 2020

Verified Purchase

works well... accidentally only provided 1v and was sending still pwm signals. after some time i sent 3.1v and it worked great. it does show up in just a bag so be careful in what you order with it as it may crush it.

Electrically fine but some bent pins.

Reviewed in the United States on June 14, 2019

Verified Purchase

The headers were not held firmly in place when they were soldered making it impossible to connect the three-pin connectors from the servo motors. Some bending with my pliers solved the problem. At that point it worked perfectly.

It really runs a bunch of servos and it's cheap and easy to use!

Reviewed in the United States on April 19, 2019

Verified Purchase

If you wrote some Arduino code to drive a servo you know how hard that can be. This little circuit runs up to 16 at once, and the example code is easy to follow. I recommend this product.

it works. easy to use. beware - no DDR

Reviewed in the United Kingdom on May 29, 2018

Verified Purchase

I got this going fairly easily. Just look up the data sheet on-line with the ic number. Very simple operation. Just send I2C address then data pattern. It works ok. But the pins that are "Input/Output" do not have a Data Direction Register. You can set a line high and the pull-up is weak, so they can then be pulled low and read back allowing use as inputs. This is not hugely aesthetically pleasing. As outputs they really need to be used as low-side if you want any oomph.

Good little unit, not to expensive, does what it’s meant to and helps with cable management.

2x16 PWM channels for a good price, use them with Arduinos, have had no issues or problems.

Good or controlling lots of servos

I've used these in my robotics projects and they work nicely. I controlled them from my Raspberry Pi Zero W using I2C.

Almost Perfect

Reviewed in the United Kingdom on January 21, 2019

Verified Purchase

Used with A Raspberry Pi to control and power four SG90 Tower servos.
Established an I2C connection straight away and was able to start moving servos in just 5 minutes.

Only flaw is the terminal blocks have a little trouble grabbing and holding the wires for the external power supply.
