DIY ESPixelStick diagram check

[fedekrum]

This is not a bug or a feature. This is a doubt.
I did the following and it just works. Awesome!!

In the diagram, there are question marks because:

1. I am not sure if I have to connect pin 1 of the XLR to the other pin not connected on the HW-519. It just works without the connection.

2. How many amps must the USB power supply have for this implementation?

3. Is it OK to power it with a USB power supply (a charger)?

4. is there something missing or wrong in my diagram?

Thanks in advance

RS485 only needs the two wires. The gnd wire is optional. It helps reduce noise on very long (300m+) runs. This configuration will draw about 500ma from the charger so a 5w (1amp) charger will work fine.

Thanks Martin.
Do you know of any virtual DMX controller on iPad or Android tablet able to send Arnet or Sacn?
I imagine that there must be something with sliders.

I use sACNview on a windows PC. They may have a Mac version.

Thanks. I was looking for something to slide with my fingers (basically a tablet)

So this is better and complete for you based on your corrections?

Tested with the multimeter, both grounds on the HW-519 don't have continuity. Do you know if this is normal?

[MartinMueller2003]

Both GNDs?
The diagram looks fine.

[fedekrum]

this two

should I connect them?

[MartinMueller2003]

No. Leave it the way you had it.
