Is there any way to connect **ws2812b (5v)** and **ws2815 (12v)** on same esp8266/esp32 ? If **Yes** , can someone draw me a connection diagram, showing which wire/pin going in where??? Note that ws2815 is behind my monitor for ambiance and ws2812b is all over my walls for music or playing with modes. so I guess both have to use different data pins. Plz, help me here. ---

You connect the ground from both power supplies, the Esp and both LED strips together. The 5v Positive goes to the 5v strips, the 12v positive goes to the 12v strips and the Esp is either powered from the 5v supply **or** from the usb port. 🙂 ---

That’s the general idea. Best if you can keep the data line from the MCU to the strip short. You may end up needing a level shifter on one or both data lines. Try it and see what you get. ---

If you are going to be using that barrel jack I would not send more than 3 Amps through it. They are not rated for more than 5A and allot of them can’t handle 5A ---

Do I need to unify the 12v ground and 5v ground as they are from the same source only going through a converter??? if i power nodemcu with my pc, do I still need to connect the **vin** and **gnd** of nodemcu with 5v power supply?? > [@Jinx](#): > > Yes looks ok. ---

If you are powering the mcu from the usb port **do not** hook 5v to vcc or you will likely damage the mcu. You still need common ground from the mcu’s ground pin, your LEDs and the power supply. If you are using a 12v to 5v buck converter you may not need to ground both sides. I still would as you don’t know what happens to the ground w/in that converter board. ---
