313:1 Metal Gearmotor 20Dx46L mm 6V Category_Grove (Arduino)/Grove Schede/Kit or you can use solderlessThese small brushed DC gearmotors can deliver a lot of power for their size. This version has a 6V brushed DC motor combined with a 312. 5: 1 metal spur gearbox. The gearmotor is cylindrical with a diameter of 20 mm, and the D shaped output shaft is 4 mm in diameter and extends 18 mm from the face plate of the gearbox. Key specs at 6 V: 45 RPM and 170 mA with no load, 220 oz in (16 kg cm) and 2. 9 A at stall. Note: the gearbox torque limit is 70 oz in
