Some critical information missing

By: Ed on 30 December 2017

This is a nicely made module that appears that it might have been originally meant for use in an audio mixer application. My intention was to use it to provide a feedback signal in an Arduino based positioning system. However, the product description doesn't mention that the potentiometer has an audio taper rather than a linear taper. This makes it unsuitable for my project but would work fine as a volume control. The fact that the item has two resistive elements is mentioned but not dealt with in terms of applicability but does make it well suited as a volume control for stereo applications. To Australian Electronics Direct's credit when I brought to their attention that the audio taper makes it unsuitable for my applications they promptly offered me a refund for the pieces I had bought.
