Gravity: Screw Shield V2 for Arduino SF_Buzzer and filter small biopotential signalsThe DFRobot Arduino Compatible Screw Shield is a terminal expansion board that allows you to screw in jumper wires to a screw terminal for a much stronger and secure connection for your I O and power pins. Feel secure with this Arduino compatible screw shield. The screw shield v2 from DFRobot also extends the power supply pins for the signal pins. You could directly plug in the sensors and the servos to the screw shield v2. The pin headers are color
