These require WhitenoiseFPV Racewire Mini to be used. They will not work with the Regular's. You solder them on to the racewire pads and then solder on your motor wires.
These are 5v addressable LEDs. They just mount to race wire and allow of easier wire management to underarm addressable leds. You will have to run 5volt, Ground, Data to these in addition to soldering to racewire.
There are pads to Allow you to wire up additional addressable 5v LEDs to the bottom of your Arms. 5volt, Ground, Data out. I use 30awg wire to run to the bottom boards.
RaceWire Mini is 8x25mm long. These Fit onto of the race wire. They solder on the motor pads at both ends. I would suggest soldering them together prior to putting them on your frame.
Warning: LEDs get extremely hot, be very careful when handling your quads with LEDs installed.
