Looks good.
You have the same pin assignments as I chose.
Edit:No positive voltage feed for the nodemcu?

I don't know yet if I don't use this:
Then I would power it with the DC connector ... -
A or a second variant with both NodeMCU power.

Hi, what is 74hct125 for?
Can i connect it directly without this thing ^^?Thank you

Hi, 74hct125 is level shifter. I strongly recommend using it to avoid flickering LEDs for low power levels.

Then I need to connect d7 and d5 to LV1 and LV4, then HV1 and HV4 to the stripe, and ground to the shifter. I'm right ?
