Hi. I can't for the life of me find a place to purchase TLC5940 chips. I see that it is possible to find places to purchase them on TI's website, but their website has 10 different versions of TLC5940; I don't know where to start.
All I want to do is expand the amount of PWMed LEDs my arduino can drive. Could someone please point me in the right direction, or tell me which version of TLC5940 they've used in projects?
