This is a replacement motor for the EEW Nano 1.1.
To replace this you will need a small Philips to unscrew the motor and a small flat head screwdriver to release the wires from the circuit board. Here is a video showing you how easy changing the motor is.
If you are installing this in the EEW Nano 1.0 you’ll need to cut away a little bit of the plastic. The video below applies only if you have the older EEW Nano 1.0.
