This Micro USB OTG Adapter Host Cable for Raspberry Pi can be used well for Raspberry Pi as well. It can also be used properly for A phone. Smart Android Phone, which has a small USB port. Don’t be fooled by the appearance of this cable, it’s not just a regular micro USB cable, but a USB OTG (On the Go) adapter. With it, you can connect a mouse, keyboard, or other standard USB devices to a USB OTG port, like that on the Pi Zero/W.
The Pi Zero/W has two micro USB ports, one for power, and the other one is an OTG port which saves space and allows normal USB devices to be connected using this cable. It’s perfectly designed for the Pi Zero, but if you’re using it with anything, make sure the device is compatible as this cable doesn’t contain any active circuitry, it only provides the physical adapter.
