DOUT 32 leds wont it get hot?

Just wondering, the 7805 will get hot when delivering over half an ampere. Lets say I use the DOUT with leds and connect 32 of them. Also asume I have all outputs activated at a certain point.

Using 220 ohm resistors will give me ( assuming led takes 1.2V) 32*3.8/220 = 0.553 ampere.

Since the module is getting is current from the 7805, and ofcourse other modules and a PIC are connected to it, wont it get very hot from this?.. anyone any expreciences with this?

Yep…all three of mine get hot.

I just banged a heatsink on em.

Great thnx Ian…I’ll make sure to sink’m too
