This is a PCB that fits the wings of the Nathan Duncan PKE model.
If you haven’t purchased the 3d model, you can find it on Etsy here.
You will need two for this kit, so make sure you purchase two of these. Be sure that you checkout the tutorials on how to wire these up with the LEDs.
The flat top LEDs are the correct LEDs for these PCB boards. You can choose from yellow (classic Ghostbusters look) or white (Afterlife).
Here is a demo of the LEDs working prior to them being installed. To see a further demo, check out the full kit page here.
