“Great little board for controlling 12 servos from an Arduino. Currently being used with developing animatronic eye movements project.
Delivery was prompt and good price.”
“I bought this to control multiple servos from the minimum pins on an arduino, and it does the job so easily.
The ability to daisy chain these is great too.
Soldering the headers on was simple, and I was up and running in no time.
Recommended.”
“Well made, easy to use with Adafruit libraries and off loads the work from the Arduino devices to the board.
To make the cards work in sync, an external clock signal needs to be applied to the pwm chip on the board. The External clock pin is grounded on all boards I have tried. Unlike other boards which uses a ground plane this board has a track you are able to cut. I was then able to solder wire to the chip(pin24) and provide an external clock(Adafruid Si5351). Using the default broadcase address of the pwm boards I was then able to restart the boards in sync and teh pwm signals did not drift.”
