The MagPi said

This expansion board not only leads to 9 micro:bit onboard GPIO interfaces

Motors like this are especially popular for use in home-built 3D printers (eg RepRap) and CNC machines

In the solar powered projects

Glideforce LACT8P-12V-05 Light-Duty Linear Actuator with Feedback: 15kgf, 8" Stroke (7.8" Usable), 1.7"/s, 12V SF_Solar Panels and the LTE FDD bands:This 12 V light duty (LD) linear actuator with a 5: 1 gear reduction can lift loads up to 15 kgf [34 lbs or 150 N] and can withstand static loads up to 250 kgf [550 lbs or 2500 N]. It has a maximum speed of 43. 9 mm s [1. 73 s] at no load and 36. 5 mm s [1. 44 s] at the maximum load. Limit switches at each end make the actuator easy to control over its full range of motion. The shaft holds its position when unpowered. This version has an 8 inch stroke
