original &lsquo;A&rsquo; into &lsquo;PWM&rsquo; and &lsquo;VR&rsquo;. &lsquo;A&rsquo; means that the speed can be adjusted. There are three ways to adjust the speed: PWM signal speed adjustment, 0&ndash;5V analog signal speed adjustment, and manual potentiometer speed adjustment.\n        <\/p>\n\n        <p style=\"font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,'Helvetica Neue',Arial,sans-serif;font-size:15px;color:#0F2533;line-height:1.75;margin:0 0 20px;\">\n          In fact, we need to use two different control boards for these three speed adjustment methods.
