Looking for a sanity check on the wiring here. Might swap Data4 for Data 3 on the pinout but this was just easier to draw because its so messy (i am sorry). Big question is do i need to bridge LED3/2 (pin 22/21). Im only doing it cause i saw a similar setup and was using it as a reference.

So how I'm seeing it, you are using Data1 to drive the accent pixel (likely a CC), and you are using Data 2 for the main blade (you'll need a 330 or 470 Ohm resistor on Data 2 if that is the case)? Also, you are using a data pad to power a motor? (not sure there is enough power there, and I think it's a negative pad), as for your question about LED4 and 5, no you don't need to bridge 4 and 5 together for a single pixel. Techincally one LED FET can power a full blade (13A rated) but the second one adds redundancy as well as reduces the strain on one. But for chassis accents you can get away with only using 1. Also, you need to match Tx > Rx and Rx > Tx. If you match Tx > Tx and Rx > Rx the connection won't work.

-If i use Data1 for the main blade do i still need a resistor?
LED4/5 are on the blade connector not a single pixel
oh sorry i goofed
its LED3/2
jagged shore
no, but you will still need a resistor if you plan to use any of the data pads aside from Data1 need the resistor for data.
jagged shore
its LED3/2
ah, then yeah, LED 2 and 3 need to be in use for the main blade.

So i do bridge LED3/2 together connected ot the - lead on the CHC_F board
jagged shore
if you are doing a single wire from board to chassis connector/pixel adapter, yeah you'll need to bridge the pads.

The ACcent LED is this one: https://thesaberarmory.com/collections/neopixels-led-strips/products/nano-neopixel-rgb-accent-led-chainable-5mm-outer-diameter which.. i THINK has an internal resistor on the PCB
jagged shore
nope, that's a cap, not a resistor.
limber hound
ah nuts
Ok so: move the Blade to Data1 and CC LED to Data2 which means the blade won't need a 330/470 ohm resistor and probably just move the motor to the 3.3v instead. Did i understand correctly?
jagged shore
not sure on the motor tbh, never used one in an install.
otherwise correct.
then of course what I mentioned about the BT module data lines.
limber hound
I believe they are correct in the diagram Rx-Tx ; Tx-Rx
jagged shore
oop, they are. nvm, I was looking at it before I was fully caffinated.

no worries, the reason i was swapping the data lines was i had read that data 1 is pre resisted on the board and the NPXL connector for the blade has a resistor on it so this way you don’t need to deal with an in line resistor. Not sure how true what i read was tho
jagged shore
no worries, the reason i was swapping the data lines was i had read that data 1 ...
actually that is true. Ugh, totally forgot the pixel adapter has the resistor. So the data 2 as main blade setup would work without needing an add on resistor.
Also means I need more caffeine.

heh no worries, looks like original wiriing will be fine then
