or you can use solderless ring terminal connectors

it can drive the ordinary small motor and N20 mini metal motor

This motor is intended for use at 12V

Zumo 32U4 Main Board (this includes two magnetic encoder discs that work with encoder sensors integrated into the main board and a through-hole buzzer)

it routes the serial signals from any board which uses the standard FTDI header footprint either to the programming PC via a USB-to-serial bridge or to any other device with a FTDI header

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
