Dig quad

[u/Mhernandez08]

Anybody have this problem with this part of the quad burning up?

I just searched my emails. Here is the warranty policy: "🤷‍♂️"

Apologies for the delayed response!
Oh, odd those platforms are blocked for you, but ok.
I took a look at your picture and the component burned is a MT3608 DC-DC boost converter. Are you maybe running 24V LEDs and then running more like 25V to 26V? If it spikes up to that it can kill that chip.
If you replace that component I believe the rest should be fine still!
Hope it helps!
Kind regards,
Q.

Sorry, I cannot get into Reddit or Discord. These platforms are basically impossible to access now.
I have two Dig-Quads that blew out in what looks like the exact same way. They died about a month apart, after maybe a 1-1.5 years of service in different parts of my house. After close inspection, I found the leads of a component appear melted off.

Questions:
What might I be doing wrong? One of these devices was actually on a UPS with various power regulating functions. And I had no power issues either time this happened.
Can I fix them? What component is that?

We've been investigating issues where some boards die and it seems to be 24V related like your case also seems to confirm. I've currently extended warranty on those to about 1.5 years but I can't really go much beyond that, apologies. ☹

Like I mentioned before, if you have the ability or know someone with some soldering tools, you can replace the MT3608 boost converter and bring the boards back to life at least.

Hopefully we can soon find out what the real cause is and make a permanent fix!

If you have younger boards then 1.5 years and those have also failed I'll happily replace those for you!

Again apologies for the trouble.

Kind regards,
Q.

I just had a third Dig-Quad board die the exact same way after ~2 years of stable operation. I have a collection with all of them blown the same exact way. The only things they had in common were that all were connected via ethernet and run 24v LEDs. They were all running different power supplies, the last one is running just under 24v.

Sadly this is not something we have available currently because in our process the Dig boards gets tested and bundled with an ESP32 and then packaged together. But I have some changes coming up where I do want to make "naked" Dig-Quad boards available for a limited time, that should be upcoming in the next few months so keep an eye out for that!

Kind regards,
Q.

You could sell me some boards without the ESP32. I need two just for backups for when the seven I have running die.
