  • Soldering

    We can solder the kit for you. It will add 3-5 days to the order processing time.
    Price is just for the service, no extra parts included.
    If you want the controllers to be removable, please include 2 packs of controller sockets + pins.

  • *

    Sorry, we don't provide the full in-switch RGB module soldering service. The modules are a big pain to solder in this kit and we could not guarantee good reliability.
