Jaycar DC Geared Motor with Rubber Wheel – 48:1 Ratio, 10V Max, Speed Encoder

Your Arduino rover's wheel motor gave up, or you're building one from scratch and need something that actually grips the surface. This geared DC motor handles up to 10VDC with a 48:1 ratio, giving you 800gf·cm of stall torque at 250mA. The bi-axial encoder reads speed so your code doesn't guess. It's a direct swap for the KR-3160 (2WD) and KR-3162 (4WD) chassis. One wheel, one motor, one encoder in the box. No acrylic case included. $18.09
