Hi I have purchased the following strip, described as : BTF-LIGHTING FCOB SPI RGB Flexible High Density LED Strip COB WS2811 IC LED Strip 5M 630LEDs/m 14W/M DC24V Black PCB IP30 Chasing Colour My strip is - https://www.amazon.co.uk/BTF-LIGHTING-Flexible-Density-630LEDs-Controller/dp/B0C48TH9WR?re…

They should just work w/281x protocol. If your PS’s are good and you have a common ground between the ESP and the strip, your next step will be to add a proper Levelshifter (not I2C).

So a 24V 200W 8A power supply connected to Red (+ve), White (-ve) then connected to the two (extra) power injection wires (red and white on led strip) … This then leaves three wires on LED Strip, Red, Green and White, I have : White (GND) connected to ESP GND Greens (data) connected to GPIO4 I a…

Yes, that will do for common ground. Levelshifter is next.

Total noob and well out of my comfort zone, any amazon links and or ELI5 articles that would show how to connect ? I assume it sits in-between the Ground and Data line from ESP → LED Strip, raising voltage from 3.2V (ish) to 5V that is expected ?

Take a look at KB section on levelshifters there’s a bunch of good info there. I’d recommend the 74AHCT125 based devices, make sure to wire all the unused inputs per the diagram and include the 100nF bypass capacitor. Don’t worry about the output resistor for your setup. As per the diagram, the l…

Ok parts ordered from amazon, soldering fun tomorrow !! Two questions if I may ? When you say inline, essentially the level shifter sits between the data line out of the ESP32 and the LED Strip, we are raising the data sent from 3.3V to 5V which is what the LED Strip expects ? In effect this is a…

Yes, the need for a levelshifter is because the entire line of ESP devices is limited to a max supply of 3.3V. As far as 5V power, the ESP board and levelshifter typically need only 1.5A at absolute worst so almost any 5V 2A supply is adequate. Some people have used a USB 2A charger or a 5V2A “wall…

Ok I think I’m nearly there, I’m using a 5V 2A Apple plug to USB in on the ESP32, that works and powers the ESP32 fine. The bit I’m confused on is : In the levelshifter diagram for SN74AHCT125 it shows 5V going to pin 4, 10, 12, 13 and 14, where do I get that 5V from ? I’m using an ESP32 powered fr…

To give things a little perspective: Pin 14 on the 74AHCT125 is the power (Vcc) pin that supplies the device. All other connections to 5V are logic inputs that correspond to Hi level. Similarly pin 7 is the power supply Gnd for the chip and all other connections are logic Lo inputs. The 5V you u…

Yep, which is what I tried after one of the low power bi-directional level shifters. Still no luck. Created this post to see if anyone has any feedback!
