DIY-Pro - How to add LED Strip for PM2.5?

#1

Hi everyone,

in the introduction Thread for the new DIY Pro enclosure/PCB, a picture with indicator LEDs was posted to reflect the current AQI.

Now I received the new PCB pre soldered, but no LEDs included, also the “shopping list” does not include any LEDs.

Therefore my question, how to add this kind of LED indicator to the new Board?

Thanks lot,
Marcel

Bump. Planning to do this with my 4.2 and a cheat sheet would be quite helpful.
