Just in case anybody finds these interesting, after building some larger scale LED setups for a couple propagation and fishroom setups I've been wanting something different than the usual
offerings from places like Coralux, Steve'sLED, RapidLED, etc. All of the boards you see offered for sale work for lower voltage builds (12-24 volts) just fine, but the LDD-L drivers are compact, easy to use alternatives to the LDD-H series for smaller builds, or when multiple smaller strings are required. I for one use them extensively for nano fixtures, or for filling in the extra colors on "full spectrum" types of builds, in conjunction with 21 volt laptop power supplies, ranging in size from 3 to 7 amps, which is plenty in most smaller to medium situations.
These can be jumpered to allow channels to be doubled up, to allow four or eight channels of control on the eight driver version, and eight channels of control on the sixteen channel version, with daisy chaining also possible for stacking boards as needed for larger scale configurations. All parts are through-hole, so easy enough for even a novice to solder up
Keep in mind these are sort-of a power-user board, and while they offer pretty good flexibility, they are not as of now compatible with the Bluefish mini- although with the use of a level shifter they would be, the fullsize Bluefish will work however. I have been primarily using the LDD-L with the Storm controller or the very nice 16 channel controller featured over at Ultimatereef- https://www.ultimatereef.net/threads...roller.784531/
Any controller using the PCA9685 PWM driver would be a perfect fit for a companion to this board.
I'm also working up some sketches for larger versions using the LDD-H drivers as well, but due to the larger physical size I'm not sure I'll put more than eight drivers to a single board to keep them affordable for small runs of PCBs. Suggestions are welcome.
