ESP8266 LED Lighting: QuinLED v2.6 PCB

It’s been a long time in the making but I’ve finally put the final touches on my newest revision of QuinLED! This makes it version 2.6 rev 1.00.Β Let’s check it out!

This post is part of a series

The index for this series can be found here.Β 

Video about the new board

To test the new design I decided to make a video about me soldering and testing one. It’s about 30 minutes long, but I show you some tips & tricks and take you along through the whole process. This video doesn’t replace the soldering tutorial perse but some of you might find it interesting anyway.

DirtyPCB Direct Order link

Most of you will want to use the direct DirtyPCB order link. This gets you 10x 5×5 boards which in turn are 20 QuinLED dimmers. With each having 2 channels that would make a total of 40 channels!

Click here to order the boards. Doing so also gives me a small kickback so that’s appreciated!

I often get asked if I don’t have a few boards to spare, no, no I don’t. I often use my boards in my own projects, throughout my home and also during workshops, so nothing to spare.

Still, I understand that you probably won’t need 20 boards, but then again, looking at the price it’s only ~12$ to get the boards anyway, just don’t use them all or give them to a friend! The other components you need all come in lower amounts (such as 5) so I think that would be the minimum to build.

Fritzing source files

As always if you’d like to order the boards somewhere else, you can download the fritzing files and gerber files here.

If you decide to use the files to make your own work, that’s fine but a link back to here would be appreciated!

Conclusion

This board design will be the last one for a while. As far as I’ve been able to test, everything is working now and as far as the design goes everything seems to be in the right spot and the trace thickness is better then ever allowing the highest power to run through them of any of my designs.

    1. They have the same properties I just have several different versions of them but they are basically the same. I haven’t been able to find any difference between them so that’s good. I noticed on some boards that there would be more whining noise then on others so I wondered if it was the MOSFET type. But as long as the MOSFET confirms to the specifications (see my previous posts about that) you should be good to go!

      p.s. Especially the gate activation voltage should be below 3.3v, often they are spec’ced for 5v which would be fine for an Arduino just not an ESP8266 as I’m using here. Chinese suppliers often get that wrong. πŸ™

      1. Be sure to get some with a low Rds, since this largely determines the amps it can handle before getting too hot πŸ™‚

  1. Hi!

    I just bought a Osram Soleriq P13 COB LED and I remembered that you had some COB downlights. Can I run it of a boost converter with voltage set a bit under the forward voltage?

    1. In theory, if you can use constant voltage (instead of constant current) to drive the COB LED you should be able to put PWM on that signal and dim the COB LED with that. That is exactly what I did with mine.

      Measure the voltage of the power supply that comes with it (It will have a range but function at a certain voltage during operation) and then just get a different (constant voltage) power supply to put out that voltage. Most frame power supplies (Like the Mean Well’s I’m using) have a voltage adjustment range. So I use a 36v power supply at 33.2v for my COB LEDs and it’s been working perfectly for me!

    1. I believe I talk about that in the video and in this article?

      But mainly it has an optimized layout, upped the power handling and the resistor implementation works if you want to use those.

  2. I finally got around to properly testing some boards that I assembled earlier in the year, and wanted to control them via MQTT. I looked around and found that espurna would be ideal (having tested that with an Ai Light), so decided to try and get espurna working for the QuinLED. There were no code changes required thankfully, just some ‘header’ and config tweaks. It built fine, flashed fine (via serial and OTA), and worked fine.
    I submitted a pull request and it’s been accepted into the dev branch of espurna, which might be useful to some readers who are looking for additional features.

    Love these boards πŸ™‚
