HI

I am working on a LED display board project of 16 * 288 matrix line, The 16x288 line consist of 9 boards of 16x32 leds. The problem i am facing is connection the supply to the boards, i have 3 concepts in mind can any one help me to finalise any one, My total load current is 2.7A @ 5V . Below is the conceptual wiring diagram i am planning to use



In confugration A the system works fine but the voltage drops to 4.0 volt, Here i want to know can i connect the SMPS output to two side of the load or it will creat some problem

In confugration B the voltage supplied to the last card is very low so the intensity of the board gradually decrease and does not give nice visualisation effect

In confugration C the wiring is too much thus creating a mesh of wires which we do not want.

Please suggest.

Thanks & regards
Santanu
