Start with cutting up the pcb - I made this sample on single sided. But duble sided is stronger
I use 5 X 8 holes - It seem to fit all my
with small border - (if 2 boards shood be next to each other (16 bit)
Solderless Bread Board

Cut the male tin square 8 + 1

Then solder in the male tin square - You can use a Solderless bread bord, as support

Then solder in all the resistors.

Then solder in all the led´s

Then test all led´s

Then solder the GND connection.

Then test all led´s

Now the board is ready to bee used in test setups.
Here a test setup with 6 pcs 8 bit shiftregisters (74HC595) and an Arduino Pro Mini clone.
