The Geek Servo motor is easy to connect and control with a micro:bit and it is designed to work in any lego compatible building brick. Even the axle mount is desinged to work with your bricks so you can easily plug gears, wheels, and other axle mounting pieces directly to the servo! 
 
The positional servo motor is a traditional servo motor, it does not rotate all the way around but moves thru a 270 degree arc.  Think of how windshield wipers go back and forth.  Use these motors to make ears wiggle, tails wag, and for steering robotic vehicles.  
 
To power this motor you will need a full 5v so the small 2 x aaa battery pack will not work.  Make sure you upgrade to the 4 x aa battery pack.  Like the motor the 4 x aa battery pack is designed to work with our Edge Connector.  Lego bricks not included.  
 
The positional servo motor is gray and is included in the micro:bit Base kit.
