Finally you want it to be SMD or TO-220 ?

I need it to be through-hole only to test my code, production will be SMD. At $20 a pop, I will probably only use 2 to test the daisy-chain logic and circuitry.


The need to drive the 7-segment LEDs has evaporated with my recent discover of the MAX7219.

I'm only driving a 2A LED strip of 3 feet now.
