I’m a complete beginner to LEDs… But I’m an avid DIY and figured jumping in would be incredibly fun. I was able to successfully solder the strip mount and sensor board. When I connect via USB to a WS2812B strip, I’m able to find and connect to my Pixelblaze with ease. However, I’ve tried switching to external power and it is not working… Attached is a photo. Any hints or leads to help me take this to the next level?
