This little brushed DC motor driver is speed-controllable, bi-directional, and has a configurable current limit that can be increased to 1A (from 0.2A) by bridging the pads on the underside of the board. You can use up to four at once, and control them independently, by changing the I2C address (configurable by cutting one or both of the address traces).
The DRV8830 breakout has an I2C interface and is 3.3V or 5V compatible. It is designed so that you can solder a piece of right-angle header onto it and then pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 6, 9).
It's also compatible with Breakout Garden, where using breakouts is as easy as just popping it into one of the six slots and starting to grow your project, create, and code.
Pimoroni have put together a Python Library that you can use to control your DRV8830 Breakout, with easy control over speed, direction, braking, and a bunch of other functions. Nice!
