Hey guys, sorry for the noob question etc etc

I'm looking to use a pico crumble board with this prebuilt led module, and i have two questions:

  1. Will i need a resisitor? My calculations say yes but i want to double check
  2. How will wiring it work? I noticed the prebuilt led module has a male jst connector so i assume i will need a female jst connector, but how does that fit into wiring with the pico, especially RE resistors?



Thanks guys,
J
