It's very well made, and comes with the only cable it needs and two propellers, forward and reverse.

The motor is very strong - given the N20 neodymium magnets in it. In fact, just rotating the propeller by hand lets you feel the magnets resisting your finger!

There's an example program on the product page showing how to control its speed too - so getting started is as simple as uploading the code to the M5Stack system in Arduino and plugging the motor in.

It's directly driven by an IO pin of the grove connector - so this little device needs a pin all of its own for each motor added? Perhaps a new version may come with IC2 support, so a bunch of motors can be connected?

Either way - it's a fun device to see some "real world" influences the M5Stack system can have! A++ =)
