Need advice about Proffie V2.2 wiring diagram first time build for four 3535-LED stripes

Hi all, This is my first attempt to build and wire a Proffieboard V2.2 for four 3535-Led stripes. After reading the Proffieboard manual and watching many related videos, I used poor knowledge to draw the circuit diagram. Due to the blade having 4 LED-Stripes, I was very confused when I drew the diagram.

Four [3535 SK6812 ] LED stripes 5V/9A/144leds
proffieboard V2.2
quad-star PCB connector(blade-side)
NPXL V3 or art beams connector(hilt-side) (the art beams pcb) I am not sure with this one, cause art beams only have one pad for ‘Negative’ ‘Positive’ ‘Data’, but NPXL V3 have double pads on PCB, might be easier for soldering the wires.

I want to use a 3.7V/5000amh/21700 battery for the saber, It can last longer. Do I need a down or Up voltage regulator for BAT?

here is my proffieboard wiring diagram, There may be some problems that I don’t understand very well…

Wire them in parallel with one data line it will be much easier and the styles will run better. Just branch the data to all 4. Same with the negative lines, you can run 4 if you want, but treat them as one blade and branch to the neg on each strip then be sure to define in the BladeConfig.


BladeConfig blades[] = {
 { 0, WS281XBladePtr<144, bladePin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3, bladePowerPin4, bladePowerPin5> >(), CONFIGARRAY(presets) },

This way the 4 strips are always in synch since they’re meant to act as one blade, just be sure to use sufficient gauge.

Thank you Fett, you said exactly what I needed~ I modified the diagram according to your suggestion. I really like your website, It’s so cool~

Does the circuit look correct to you? I felt so excited that the build day was finally coming.

Not if you’re doing parallel. You would only have one data line, not 3.

Thank you for your guidance, really appreciate it. But I am not quite sure… :sweat_smile:
I branched 4 30-awg Data into 4 data pads on proffie. In addition to the data1 pad, the data2-3-4 uses a 470-ohm resistor and then connects four data wires with one single 24-awg wire to hiltside PCB.

You only need 1 data pad if you’re running in parallel, you can’t branch multiple data pads into one blade. That’s not how the data works. Just use data1, it’s pre-resistored.

Got it. Thank you for your patience and help, I understand the connection of the data pad now :face_holding_back_tears:, only need the data1 pad if I use multiple LED stripes as one blade. For the LED2-5 negative pads, do I need to wire all 4 pads together to the hilt-side PCB or use one sufficient gauge just like the data pad connection?

TBH I am not familiar with the connector you’re showing, most neopixel blade connectors have multiple pads for - and + to be able to handle the current needed. Your connector may not support 2 strips let alone 4. I would look for a connector that can take multiple - connections and wire straight from an LED pad to the connector for - .

Your current connector probably won’t support the current from multiple pads. If your connector can’t support enough current your blade will not work correctly and/or have other issues like excessive heat etc.

Your advice is of great help to me, I will look for another type of connector such as NPXL V3 or other 11-pin types that have a double pad for each port. Prevent mistakes, even though mistakes are learning… another silly question is could I use a 3.7V to 5V battery booster plate for this build? because the 3535-LED stripe each one is 5V/9A,and A 3.7V battery with 4 strips will not be very bright.I don’t know the circuitry, or whether this is feasible and necessary.

Proffieboard uses 3.7 batteries, not sure what you’re asking. I’d recommend reviewing the manual.

I will read it carefully, thank you for your help~ :pray:

It is theoretically possible, but not recommended.
It’s not going to make the blade brighter (just hotter) and finding one that is powerful enough and small enough is going to be tricky.

Thank you Prof~I will not use it in builds.
