The picture below shows how to mount Zero4U on Raspberry Pi Zero W, with the 
ferrite ring between them. 

 

Remarks: 

this USB hub has only one transaction translator (TT) for all downstream 

USB ports. Please try not to connect any USB 1.1 device to the USB hub; otherwise 
all devices on the hub will be slowed down to the USB 1.1 speed (12 Mbps). If you 
only connect USB 2.0 devices to this USB hub, all of devices on the hub can work with 
USB 2.0 high speed (480 Mbps), if they support USB 2.0 standard. 

If you want to connect this USB hub to other Raspberry Pi models, you will need a 
USB - mini USB cable (not included in the package).
