Originally published at: How a Multi-Board LED was Reverse-Engineered | Sierra Circuits
Sierra Circuits reverse-engineered an LED controller prototype with multiple off-the-shelf modules and consolidated the design into a single PCB. The redesigned 4-layer board integrates wireless communication, lighting control, USB-C power delivery, current sensing, and high-current LED switching into a compact form factor. In this case study, you’ll learn how our designers addressed key engineering challenges, such as power distribution and mixed-signal isolation, to convert a complex prototype into a manufacturable printed board. Highlights: To consolidate the prototype into a single printed board, our engineering team: Reconstructed proprietary LED driver boards and recreated the schematic. Designed a dedicated 24 V power…
