The Cookie I/O expansion shield is designed for beginners to electronics. The shield is directly compatible with the gravity series. We have implemented fail-safe systems to prevent bad connections from destroying the board. The board is protected from reverse voltage input. And connector ports only accept connections the correct way around. These fail safes make the board ideal for beginners and classroom settings - no need to worry about your students making the wrong connections!
