TT Gear Motor — 3–12V DC, 1:48 Gear Ratio, 800gf·cm Torque, Arduino Robot Chassis

The TT gear motor (also known as the "yellow motor" or "smart car motor") is the most widely used DC gear motor for Arduino robot chassis, smart car kits, and DIY wheeled robots. With a 1:48 gear ratio delivering 800gf·cm of torque and a wide 3–12V operating range, it provides the right balance of speed and torque for two-wheel and four-wheel drive robot platforms.

Why Choose TT Gear Motor?

✅ Universal robot chassis standard — fits all standard TT motor mounts and brackets
✅ 3–12V wide range — works with 3.7V LiPo, 5V USB, 6V AA pack, or 12V supply
✅ D-shaft output — compatible with all standard TT wheels (65mm, 68mm)
✅ EMC capacitors — reduces PWM noise interference on microcontroller
✅ Low cost — most affordable motor for robot chassis builds
