custom 80 pixels led tapes on 15mm width flexible pcb

An old friend from England emailed us if we could make 80 pixels sk6812 flexible led digital tapes on 15mm width board for their piano case.

As we know, sk6812 led is single SPI signal that normally couldn’t make 4 pads on board.

What we did an extra circult (DR)from top to end for client special using.
