Hola @vapy-
It sounds like you’d like to develop your own LED driver board, that accepts servo-style PWM input to control brightness? It is possible to purchase just the PCBs of the Lumen. Generally, this topic has been discussed on the forum before - see this thread, and this one as well. . When searching for this topic, I see we’ve discussed this before… Are you working on your project to convert a Teledyne ROV still?
