hi,
I have some questions:
-is there a schematic for wemos d1 mini?
A fritzing schematic style would the best.
I can only find a schematic for a total diy 8266 solution.
I would like one ws2812 output and one dmx output. On how to connect the data line for the pixels, and the dmx module?
I would like to use this dmx module

Wich side is the esp side and wich side the dmx out side?

In this schematic the title says pix and dmx but i do not see a connection for the pix data line?

-I see there is also an dmx input option. Is it possible to use this product to recieve dmx from my lighttable and translate this to pixels?

Feel free to email me at [email protected]. I can definitely send you a schematic for a D1 mini.

In response to your other questions:

  • The module you've linked, the side with DI DE RE RO, is the side for the ESP. The other side, which is labelled GND A B VCC is the side for DMX.
  • In the schematic you've attached, the pixels are driven using the IO2 (for port B) and TX (for port 1). Be careful not to enable DMX output on these pins, however, as this could damage your WS2812B LEDs. I'd recommend using the convert_max485_to_pix.png schematic linked here as an extra safety feature.
  • No, it is not possible to receive DMX and then convert it to pixels. You can only use it to output pixel data. Can I suggest you look at the WLED project for that? Linked here.

I have unofficially taken over this project, as Matt seems to be offline / not contributing to this project anymore. We sell a version of this project on our website: expanseelectronics.com, and you are free to send us an email at any time with any further questions.
