TT Motor Bi-Metal Gearbox - 1:90 Gear Ratio

TT-format bi-metal gearbox DC motor with a 1:90 reduction ratio, roughly double the torque and half the speed of the common 1:48 variant. Suited for slow, high-torque robot drive applications.

Motor terminal A
One of the two brushed DC motor drive terminals. The Adafruit product page states this is a basic motor where voltage goes in and rotation goes out, powered from 3VDC to 6VDC; reversing polarity reverses motor direction.
Type · PowerVoltage · 3VDC to 6VDC drive voltage, per Adafruit product page
Motor terminal B
The other brushed DC motor drive terminal. Use with Motor terminal A from a DC motor driver or supply; no encoder, speed control, or positional feedback is built in according to the Adafruit product page.
