These boards can be connected in parallel or series, so you can daisy chain as many as you want off of one driver. Each Helios I board is rated at 130W max, running 48v; we recommend 120W @ 48v / board if you choose to piggyback the driver.
There's a guy who's done some crazy builds with our boards, like mounting them onto baking pans instead of buying a heatsink (I think he deleted it though). Here's some of 'em on IG:

I've been insanely busy... crazy week for us; Steve has literally been falling asleep while on the phone with me. I hope you all stay warm and enjoy your Thanksgiving!
