Stemedu TT Motor Electric Gearbox 200RPM 3-6V Dual Shaft Geared Magnetic Motors with Plastic Tire Wheel Ratio 1:48 DC Motor for Arduino Car Chassis (Pack of 2 Sets)

Good product for school project

I received two different wheels. One wheel fits both motors. The other wheel fits neither motor. One wheel's axle hole is 2.99mm interior. The other wheel's axle hole is 3.40 interior.very poor quality assurance

So you've built a motion sensor. Or a collision avoidance device. And you've attached a camera. What now?What now is you make that creation mobile.Imagine you have motion detection robot that roams your house looking for motion. Like a Roomba with a PIR on it.Or a spy cam to annoy your sibling.Or a device that roams the halls, checking to see if your employees are at their cube.Or attach a laser to your NodeMCU, make it mobile with these wheels and really annoy your cat!Get these motors! You can configure them for single wheel or dual wheel operation. I like the dual wheel myself.There a multiple mount points on the gear housing for you to bolt them into the main chassis of your device.The video is not the idea condition/demo. Somehow, I burned up both of my LN298 Motor Driver Modules. But I wanted you to see these, and start thinking about what YOU could do with them!Once again, Stemedu delivers the goods. These motors are as advertised. You should probably buy two pair, which would give you 4WD. Arduino Sand Rail, anyone?

They don't work well at really slow speeds unless you have higher current power supplies provide the power. Other than that, they are fine. They respond well to H-Bridge control.

Did not work
