5V 220RPM Full metal gear motor GA12-N20 waterproof motor 3V to 9V


The plastic head on the motor shaft can be easily taken out.
The output shaft and back of the motor are waterproof and protected, so I believe that most of the disassembled motors are in good condition.

Output shaft diameter: 3 MM (2.45MM with flat position)
weight is 14g
