Always check the specific variant's operating voltage before connecting to a power source.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use the N20 gear motor with an Arduino or Raspberry Pi?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The N20 micro gear motor is highly compatible with Arduino, Raspberry Pi, and similar microcontroller platforms. Simply use an appropriate motor driver module (such as an L298N or DRV8833) to control speed and direction from your microcontroller's GPIO pins.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between the RPM variants?\u003c\/h4\u003e\n\u003cp\u003eA: RPM (Revolutions Per Minute) determines how fast the output shaft spins. Lower RPM variants (28–60 RPM) deliver more torque for moving heavier loads slowly, while higher RPM variants (150–300 RPM) spin faster but with less torque. Choose based on whether your project needs slow, powerful movement or faster, lighter rotation.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the gearbox truly all-metal?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, these N20 motors feature a full metal gearbox (reducer), meaning all internal gears are made of metal rather than plastic. This results in greater durability, reduced wear, and better performance under load compared to plastic-geared alternatives.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What voltage should I use to power the N20 gear motor?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Most N20 gear motor variants in this listing operate optimally at DC 5V, with a compatible range of DC 3V–6V (the A2\/60RPM model supports up to 9V, and the A4\/150RPM model works down to 1.5V).
