The shield is directly compatible with the Boson kit. 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! Features      6 x PH2.0-3P interface digital ports: D3, D5, D6, D9, D10, D11 6 x PH2.0-3P Interface analog ports: A0 - A5 Two I2C ports, PH2.0-4P Interface 5V or 3.3V power supply (selected via power jumper cap) Size: 58 * 52 mm / 2.28 * 2.04 inches Pin Definitions    Details Digital & Analog     "D": represents digital signal "A": represents analog signal One of the biggest benefits of the I/O expansion shield is increased power and GND pins, allowing you to connect more sensors. * Green: digital signal * Blue: analog signal * Red: VCC * Black: GND  This is DFRobot's Gravity Interface. Digital and analog connections are easy to recognize and support most of DFRobot's I/O expansion shields and modules. Search "Gravity" in the DFRobot store to find compatible modules. 3.3V / 5V Power Switching The shield is compatible with 3.3V and 5V logic. Select desired voltage by shorting either the 3.3 or 5v pins as pictured.
