Experience like this is why this community rocks. Intrigued by Adair21’s answer, I read around the web to understand better - I didn’t realise there could be so much tolerance in LED forward voltages!

As a result, when in parallel/at the same drive voltage, different currents drawn = different relative brightness. Outside of independent resistors, you’d need to get lucky with matched emitter tolerances or just run above moonlight so that the difference is less noticeable.

Maybe it’s a reflection of the cost of the KD boards?

Hello! If you don’t already have a Wurkkos TS10, get one and have some fun with the Anduril 2 UI 😇
