The Raspberry Pi Zero W is the RPi line's second model of a compact single-board computer. The dimensions and basic technical characteristics of the Zero W were carried over from the previous Pi Zero, but it also received an embedded Bluetooth and Wi-Fi module. This increased its utility. The Pi Zero W is based on a 1GHz Broadcom BCM2835 single- core with 512 MB RAM. Unlike previous Raspberry Pi models, which used a standard HDMI plug, the RPi Zero utilizes a mini HDMI connector to save space. To connect the Zero to a monitor or television, you will need a mini HDMI to HDMI adapter you can get one by clicking here

How to Start with RPi Zero W:

Traditionally, the Rpi 3 and other variants have had 2-4 standard size female USB ports, allowing for the connection of a range of devices such as mice, keyboards, and WiFi dongles. The Zero uses a USB On-the-Go (OTG) connection to reduce space once more. The Raspberry Pi Zero is powered by the very same Broadcom IC as the earlier Raspberry Pi A and A+ variants. This IC is directly connected to the other end of your monitor or television's HDMI port.

Use the micro USB connector to attach the USB OTG cable to the Pi Zero. Connect your dongle to the regular female USB end if you have a keyboard/mouse combo. If you want to connect your mouse and keyboard to the USB OTG cable, you'll need a USB hub.

Make sure your microSD card contains a valid Raspberry Pi image. Insert the microSD card into the MicroSD slot.

Power your Pi Zero via the micro USB power input.
