I'm designing for a maximum 48V supply in all cases on the drivers, so your math is just fine. However, the Violet channel is a bigger issue at Vf = 20V, limiting to two.

Going to need to re-position the RJ45 - this is far too deep for my liking
Trying the side mounted jack - probably a better use of space

ahh yup your right forgot you had 5 Violets, so you are limited to 2 pucs. those semiled violets are 3.6 each.
just spit ballin here. but just a thought. add connectors on either side of the board letting you have a puc on either side. mount the whole assembly on a 12in heatsink from Rapid LED and you have something with a great spectrum that will put down more par than most name brand lights on the market.
one thought since your hitching your product to reef pi. why not incorperate it right into the driver board, prolly adds a bit of complexity but you could then change it to being kinda a "hat" instead. reefpi mated right to the board. just have a power input for the light, and a rj45 for daisy chaining more "slave" lights.
honestly I could see a full blown light you could sell with Ranjibs blessing. a "designed" for reep pi product line

Very nice idea for a double-up!

Do you have a better RJ45 or are you using the same ones on the PWM converter?
I'm not sure what sort of thermal layout here but I'd imagine you want that chip seated firmly. The RJ45 is pretty nasty and I had to mount it off the side of the heatskink. I like where the design is going though. Anything that can be plug and play is a win win for DIY.

Different! It’s fully surface mount but has two guide pins. I really didn’t like the PWM converter RJ45 much
. That’s what I get for picking on cost.

That makes two of us! It works well though - just a FYI.

Full disclosure: I was still dialing in my lead free reflow process when I first made the converter (before sitting on it a long time), so I was having problems with the surface mount jacks getting far too melty. I’ve since converted to a heavy convection oven which doesn’t turn everything it doesn’t like to a crisp. Leaded solder would have been fine as the temps are much lower.

I really like where this puck is going. This would be great for like a module style light. I know absolutely nothing about any of those boards,its seems so mind bending lol.
May I derail this a hair,do you have any of the AcroStrips laying around ?

Yeah - same. I like the direction. I'm already 8 acrostars in so I can't keep swapping things out 
However, if the color spectrum and control continues to look promising - depending on the number of limes - I would be willing to try two of them in the middle of my tank. I think I could get some nice color that way.

I have a small quantity of blanks I can always load up - let me know if you're interested.

Working on the "injector" for the RJ45 side of the drivers. This is the "power side", the logic side has USB, 0-10V and PWM inputs.
5mm terminal block, DIN4 for power, and a standard 2.1mmx5.5mm for power inputs should cover the majority of the supplies out there.

You know, this is going to make connectivity a lot easier, less prone to errors (that could just be my issue though), and 100% neater all around. I need to stop watching this thread because it is just going to make me re-do everything

Thats the idea
. It will be awhile to get this going, as it does require some firmware work on several components to handle all the negotiation and setup parts, in addition to actually making a usable driver and setup tool for PC/Mac/Raspberry Pis.

So,all of this is gonna be mass produced for consumers or ?
OP
OP
For some scale of mass (where its super niche, but exists in quantity > 1). I'm trying to target cases of large systems or canopy retrofits where I think it fits nicely in. Current capacity to handle lots of mechanical design is not there
