      • If a top connector is needed to stack additional TinyShields, there is also the 16 Edge LED TinyShield which has 16 LEDs and a top connector.  
      • The LEDs are hooked up using Charlieplexing, a technique for driving many LEDs with only a few IO signals.  See the tutorial to learn more about this and use our free library to control these easily.
