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.
