The guide is drafted. During verification, I found two safety-critical details to correct: LED resistor sizing must use the maximum-current corner, and OE does not guarantee LEDs are off with the default output configuration.
Created the PCA9685PW,118 Application and Usage Guide in the project files, covering all seven requested sections with citations, resistor calculations, and startup guidance.
No verified drop-in replacement was found; two alternative candidates remain explicitly marked unverified. Before applying the examples, confirm your LED specifications and supply tolerances, and recheck distributor availability.
