WS2811BladePtr<97, WS2811_800kHz | WS2811_RGB, blade2Pin, PowerPINS<bladePowerPin1>>()

First argument specifies the number of LEDs in the strip
Second argument specifies configuration options that are specific to the LED strip

Color order onfiguration options:

WS2811_RGB
WS2811_RBG
WS2811_GRB
WS2811_GBR

Data clock rate configuration options:

WS2811_800kHz
WS2811_400kHz
WS2813_800kHz
WS2811_580kHz
WS2811_ACTUALLY_800kHz

Data pin that is used to drive the specific LED strip:

bladePin
blade1Pin (ProffieBoard)
blade2Pin (ProffieBoard)
blade3Pin (ProffieBoard)
blade4Pin (ProffieBoard)
blade5Pin (ProffieBoard)

On a teensysaber, pin 8 and 9 can be used if not used as a serial port.

FET transistor output that enables power to the LED strip:

bladePowerPin1
bladePowerPin2
bladePowerPin3
bladePowerPin4
bladePowerPin5
bladePowerPin6

If no option is set Pin Array object is created for bladePowerPin1, bladePowerPin2 and bladePowerPin3

Addresable LEDs have 4 signals (WS2813 have additional bypass line)

VCC
GND
DATA IN
DATA OUT

The ProffieOS supports the following types:

WS2812
WS2812B
WS2813
PL9823
SK6812

Protection

As the led strips get immense amount of current, it is good suggestion to use thick wires for VCC and GND to avoid heat/power loss.
It is good practice to put large electrolytic capacitor ( 470uF to 2200uF) as close as possible to the strip to avoid spontaneous current draws, that might occur.
In order to protect the first addressable led in the chain from voltage spikes and additionally to make sure those spikes don't disrupt the integrity of the communication signal, a series resistor must be put as close as possible to the LED strip (100ohm to 470ohm)

Neopixel

NeoPixel is Adafruit's brand of individually-addressable red-green-blue (RGB) LED. They are based on the WS2812 LED and WS2811 driver, where the WS2811 is integrated into the LED, for reduced footprint. The control protocol for NeoPixels is based on only one communication wire.
