31:1 Metal Gearmotor 20Dx41L mm 6V CB with Extended Motor Shaft SF_Wireless Kits There's also a cut out

There's also a cut out to allow a 40-pin IDC cable to the GPIO breakout pins on the Pi and pass it though the case

it is strongly recommended to add a temperature sensor to measure the temperature and achieve automatic temperature compensation

avoid overheating and speed reduction during full-load operation
