<div dir="auto">Yes, basically the same as those on Adafruit. I do think it is the supplies on the display itself. Going to reroute power and ground to it and add some caps and isolation. We'll see. And I'll let you know.</div><br><div class="gmail_quote"><div dir="ltr">On Sun, Sep 2, 2018, 4:58 PM Eric Brombaugh <<a href="mailto:ebrombaugh1@cox.net">ebrombaugh1@cox.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">OLEDs and WS28xx RGB LEDs all make a horrible racket due to their large <br>

regulators & bypassing are needed - large caps and possibly even LC <br>
