2 * 74HC245 octal bus transciver
2 * 74HC138 3-to-8 line decoder, inverting
8 * 74HC595 8 bit serial IO shift register
1 * 74HC04 hex inverter
8 * MW4953K dual P-channel MOSFET

power usage

Please supply 5V directly to panel (you might want to route it from there to Arduino) because it draws 2.351 A with all LEDS lit.
