LDD-H designs for 4/8up are done, just need to be tested.
Great - I'll get some done and let you know how I get on. Again - thanks for sharing

Do you plan to sell any LDD-H boards?
I've never used the LDD-L what are the advantages?

Once I finish the testing I'll likely sell some, yes I will also post up design files.

LDD-L is much smaller, a little cheaper, but only goes up to 700mA and 36 volts (unless you go for the higher power ones, then you may as well use the H series) they work well for conservatively designed applications like nano builds, refugiums, etc, or just general shorter strings of LEDs. If you use nice efficient LEDs like Luxeons they are very useful indeed. You can fit three of them into a footprint that's just a hair larger than a single LDD-H

They are slightly less efficient and can get quite warm! I know the LDD-H gets warm as well, but IME the LDD-L a little more so. Could be my imagination as they are a bit less efficient so will get warmer, but the difference is probably not enough to notice by touch.

But I always feel they are hotter. I still love them tho, just because of their size (altho being cheaper is also good!). I've just used another of these boards on a little RGBW set up on an ESP8266 for decoration/toy

Lingwendil - if you feel like tweaking the 4up design? An extra pair of headers alongside the the PWM headers for GND - just to make it a bit easier to tie in the ground from a controller. Not too difficult as it is, I just thought I'd suggest it in case you agreed it would be easier.

I for sure will be doing that, the plan for the first revision is to basically add a ground pin on either end of each row for them, similar to the LDD-H boards. I also will try to incorporate a 3 pin SMPS 12 volt regulator on the LDD-L boards, as they are affordable enough that it would be a handy feature on the 8up boards at least.

Initial testing shows that the LDD-H 8up board works well, but I'll give it a few days to run in before I release design files.

Cool - and (again) thanks

One of the things I'm doing with this little RGB set up is playing with html, JavaScript and currently websockets (may move to Ajax) which are the bits I need to get used to, to migrate the controller code onto a WiFi interface

I'd be doing it now, if it wasn't for the fact that the 15 year old girl is playing Fortnite on my PC instead of me being able to get at it to do some coding

Feature request- add a time slot feature for simple on/off control of accessories like fans, CO2, etc. A simple time on/off sort of thing would be super handy! That way the dimming channels aren't used up to do it...

Shouldn't be difficult I would say post in the controller thread about it tho, to make sure I don't forget.
