This is a universal sensor adapter that can be used by digital and analog input modules, converting sensors and other modules to the Gravity standard for easy connection to your projects. In this latest version, DFRobot has added a 10K resistor between A & B and A & C respectively, so that youdon\’t need to wire an additional resistorif your chosensensor requires a pull-up or pull-down resistor. This terminal provides a much easier way to connect a switch or any modules that require a pull-up/down resistor prior to connection with your microcontroller. Connection Example – DFRduino UNO R3 Specifications Voltage: +5 V Current: <1000mA Size: 22 x 34mm Resources ProductWiki Schematic Package Contents 1x Terminal Sensor Adapter V2.0
