Wow, that’s an exact clone of your board. :shock:
I can understand your choice to remove all the source files, too bad for us hobbyists but I can totally understand it from your side. It’s really not okay that some chinese company just steals your designs and sells them, you can’t even take legal ...

Sorry for responding in English!
It's been a while since I've been around here and I wanted to build another node for a summer project (something with a lot of dmx led panels). I saw that you removed all the source code from your website and was kinda shocked to read this. I can understand it after ...

Hello,

Last year I built the Octo node with a bare PCB I ordered from Mr. Radig as a hobby project.
So far it had various issues (dropouts in dmx signal etc) and I can now say I solved it. It turned out to be a fake/relabeled LM2596 chip from China. These chips are probably relabeled LM2576 which ...

It's not really a bug so don't know if it will be 'fixed'.
Just change it in the source, recompile and you have a changed universe. Not the most convenient way but works just fine.

Hello,

You have to change the universe in the source and then recompile it.
It's hardcoded afaik.

- Solved already

I have built the Octo node (thank you Mr Radig for the PCB!), but ran into an issue with the ENC28J60 chip running hotter than with my other projects. Now after some investigation I found out that the newer chips (B5 and higher, which are all the ENC28J60-I/SO chips, not the older ENC28J60/SO) need ...

Off-topic post;

Have you seen this Mr. Radig? http://hackaday.com/2015/07/13/new-part ... 66-killer/

Looks like a good module! And it has the STM32F4 core, like the Octo node.
Much more powerful processor than the ESP8266 so more power for processing (more universes?).

Are you planning on selling these pcb's? It looks great!

Hello everyone!

I'm reporting back to respond to my last message.
I've solved all troubles with the node. It turned out all the problems came from the network module power supply. The power supply to it needs to be stabilized because it has a lot of peak current. I didn't account for that with my ...

I'm almost embarrassed to post again but I'm kinda lost :oops:
I'm experiencing exactly the same issue again, I thought it was solved.
What I've tried already:
- Replaced the STM32F407 for a new one
- Replaced the network module, the one in the video has a 3.3V regulator on it (I have 5 different ...

That explains everything, thank you!
Do you use any other external hardware except the voltage regulators?
I'm using the LM2596 for powering the MAX485 drivers because they use a lot of current when fully loaded (almost 600mA).

It didnt really like 3v from the discovery board either, wasn't this an issue for you? On the project page I saw that you used the 3v from the board, which measured around 2.9v on my board which is too low, ENC28J60 needs atleast 3.1v from what I've read.

I've solved the issues.
The problem was the power supply to the ENC28J60 board, needed to be stabilized, seems to be a critical thing with these boards, too low voltage gives issues and it doesn't really like 5v either (it's 5v tolerant but it didn't work correctly under 5v).

No, any other user and I am have no Problems with the software. I Thing you have a problem with your Hardware.

I've narrowed it down to being a communication problem between the network module and the discovery board. I only have 1 type of ENC28J60 board around here (the same one as you show on ...
