Setting up the Raspberry Pi Zero W

The steps to install the Raspbian OS onto a microSD card are exactly same as those listed already for the Raspberry Pi 3B+ in the section Installing Raspbian OS on an SD card. Once you have your SD card ready, follow these steps to set up the Raspberry Pi Zero W:

1. First, insert the microSD card into the SD card slot of the Raspberry Pi Zero W.
2. Connect one end of the mini HDMI to the HDMI connector (H2HC) inside the HDMI port of the Raspberry Pi Zero W, and the other end of H2HC connector to the HDMI cable.
3. Connect the OTG connector to the Micro USB data port—not the power port—and connect the USB hub to the OTG connector.
4. Connect the keyboard and the mouse to the USB hub.
5. Connect a 5V mobile charger or a battery bank to the power unit's Micro USB port.
6. Next, connect an HDMI cable to the HDMI port of a TV or a monitor.
7. Connect the mobile charger to your mains supply to power the Raspberry Pi Zero W. You will then see the green LED blink for a period of time as the Raspberry Pi Zero W turns on. 
8. If you have connected the HDMI cable to your TV, select the correct HDMI input channel. The following annotated photo shows the connections mentioned here:

1. To shut down the Raspberry Pi, press the Raspberry Pi icon and click on Shutdown. 

Now that it's set up, let's connect our Raspberry Pi Zero W to a laptop.
