This small electric motor is a general-purpose motor, ideally working with batteries or solar cells, a great alternative to a rusty or damaged DC gear motor on the device. Used for electronic fans, electronic machines, cars, robots, Arduino projects, etc. With EMC, it features strong anti-interference capability and does not cause any interference with the microcontroller unit. Large quantities over 200 from YO IOT IC, two sets of DC gear motor and tire wheel for smart Arduino robot projects with 3 volts - 6 volts DC (yellow) (as shown in the pictures)
