Spend a few extra pennyies and take the best. |
* SMT parts take practice to work with, so beginners should focus on DIP package parts with <= 40 pins. On the other hand, SMT parts can yield simpler and smaller PCB designs so they are worth consideration even for a hobbiest. | * SMT parts take practice to work with, so beginners should focus on DIP package parts with <= 40 pins.
