i builded a plattform for my ESP, Level Shifter for WS2811.
- ESP 8266
- Level Shifter SN74AHCT125N
- WS2811 Stripe (https://www.amazon.de/gp/product/B01CNL6MVY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1)
3.3 Logic in is connected with D4 of ESP 8266
Logic out goes to data in of the stripe WS 2811
The Stripe is connected to 12v
The ESP get the Power of 5V in on the board.
The Software is running and i can change all in the Webgui. But i dont get any light.
I flashed the WLED_0.11.1_ESP8266.bin without any changes. The ESP boot correctly.
I tried without shifter, not working
My problem is: The Stripe isnt light up.
With my Multimeter i checked Voltage. The End of the Strip has 11,94v, all Lines are ok.
What i did wrong?
Green Line is GND, connected to Shifter GND, 1OE and GND ESP
Red Line is 5V+, connected to VIN ESP, VCC Shifter
Red Circle is D4 to Shifter 1A
Yellor Line is 1Y to Stripe.
