I’m new to electronics, I’ve never assembled esp/arduino.
I decided to build an address strip with an ethernet controller, without wifi.
I settled on WT32-ETH01.
I’m planning to build a light like this:
WT32-ETH01 with WLED firmware
LED strip 5 meters at 24v ws2811 CCT FCOB 10w/m
power supply 24v 100w (or 72w)
power supply 5v 1a
I plan to power the tape directly from a 24v power supply.
Or is it possible to connect the tape directly without these boards, as in the diagram?
Have I connected everything correctly in the diagram?
Is this where I connect GND from the LED strip to the controller?
+1 on a proper levelshifter, either of the boards you linked should work.
Note, those are just header boards, they don’t include an actual ESP32.
Also the 1st is designed specifically for the WT32-ETH01, the 2nd is for another common series of board. You’ll have to check the pinouts to see what works.
The general idea of powering the MCU from its own power supply is good, you just might want to choose a 2A or even 3A 5V supply. The WT32-ETH01 boards have been known to be somewhat power hungry.
From your previous links, both those boards have the '125 chip builtin. They have it wired on 4 of the GPIO outputs to raise the data level from 3.3V (standard ESP) to the 5V TTL that LEDS require.
