Hello,
I am designing a simple board to drive an RGB LED. I am then looking to take 48 of these boards and connect them in a 4X12 array.
The chip I have selected to drive these smaller boards live on the main board with a mirco. There will be 12 driving chips, Each chip will drive 4 of these smaller boards. I am looking for a way to only have to spinout one modular board.
I am looking for a crafty way to transfer traces from board to board.
For my first thought, I am imaging inorder to make this modular I will have extra data traces on 2nd 3rd and 4th boards in the chain of 4 boards. The 1st board will use all four, the second board will only use the traces that drive board 2 3 and 4 while the third board will only use the traces that drive the 3rd and 4th boards.
I am looking for feedback on the method I am considering, any other ideas/wisdom that is out there and for tricks to maintain these floating traces.
I am not sure if this is too clear, please reply with questions
Thanks
Eric
