Frequently asked questions
Can I power it from a single 3.7 V Li-ion or LiPo cell?
Yes, the rated range of 3.7-4.2 V matches a single Li-ion or LiPo cell. Drive it through a transistor or MOSFET from a microcontroller, because most microcontroller pins supply only a few tens of mA while the motor draws about 0.08-0.1 A.
How should I fit the propeller without damaging the motor?
The listing advises pressing and holding the back of the motor while pushing the propeller onto the shaft. Supporting the motor body prevents the bearings from being damaged.
