## Description

Perhaps you've been assembling a new robot friend, adding a computer for a brain and other fun personality touches. Now the time has come to let it leave the nest and fly on its own wings– err, *wheels!*

These durable (but affordable!) plastic gearbox motors (also known as 'TT' motors) are an easy, low-cost way to get your projects moving. This is a **TT DC Gearbox Motor** with a gear ratio of **1:48**, and it comes with 2 x 200mm wires with breadboard-friendly 0.1" male connectors. Perfect for plugging into a breadboard or terminal blocks.

You can power these motors with 3VDC up to 6VDC, they'll of course go a little faster at the higher voltages. Adafruit grabbed one motor and found these stats when running it from a bench-top supply

- At **3VDC** Adafruit measured 150mA @ 120 RPM no-load, and 1.1 Amps when stalled
- At **4.5VDC** Adafruit measured 155mA @ 185 RPM no-load, and 1.2 Amps when stalled
- At **6VDC** Adafruit measured 160mA @ 250 RPM no-load, and 1.5 Amps when stalled
 
Note that these are very basic motors, and have no built-in encoders, speed control or positional feedback. Voltage goes in, rotation goes out! There will be variation from motor to motor, so a separate feedback system is required if you need precision movement.

Comes 1 x per order, with just the motor + wires. You *cannot* drive these directly from a microcontroller, **a high-current motor driver is required**! [Adafruit recommend Adafruit's DRV8833 motor driver for these motors](https://core-electronics.com.au/adafruit-drv8833-dc-stepper-motor-driver-breakout-board.html), as it works well down to 3V and can be set up with current limiting since the stall current on these can get high. [The TB6612 can also be used](https://core-electronics.com.au/search/?q=tb6612), it's on Adafruit's shields and wings, but you'll need to supply at least 4.5V - which is what you'll likely want to run these motors at anyhow!

[Adafruit have a range of wheels, add-ons and accessories for these motors](https://core-electronics.com.au/search/?q=tt%20motor) so you can bling out your bot just the way you like.
