Grove Atomizer connections

Hi, I would like to connect Grove atomizer and set at full fog speed. Do I just connect 5V and Gnd? Do I need to connect anything else to 5V? I do not wish to control speed now for experimenting. Would try later?
Thanks,
Don

It is dangerous to connect directly to the power supply, which may burn out the hardware. I suggest you use the 5V level of IO port.
