The Raspberry Pi Zero W is an updated version of the Pi Zero v1.3. With an inbuilt wireless LAN and Bluetooth, the Raspberry Pi Zero W designed with high flexibility and compact-sized. This is possible with mini connectors and an unpopulated 40-pin GPIO, allowing you to use only what your project requires. BCM43143 WiFi chip built-in to your Raspberry Pi Zero and also Bluetooth Low Energy (BLE) on board making the Pi an ideal for making IoT projects. Even though this module consists of an inbuilt Wi-Fi chip, it is quite minimal and requires only a few accessories to turn it into a computer. But its Raspberry Pi Zero W setup is quite complicated compared to another pi.
It offers great connectivity for a micro SD card slot, a mini HDMI port, two micro USB ports (one for power, one for USB), and 512MB of RAM. It has a single-core 1 GHz processor chip, defined as the heart of this module.
A high-quality 5V 2A power supply cable allows you to power the Zero from a wall adapter. In case of directly charging from a computer USB port, the voltage often sags and can cause SD card corruption. Mini HDMI to HDMI Adapter helps to convert the Zero to a standard sized HDMI jack. Thus we get 1080P HDMI video with audio out from the computers. USB OTG Cable allows to plug in the normal USB device such as Wi-Fi dongle, USB hub, as well as a unique CSI camera cable into zero. Whereas the USB Console cable – connect the wires to the GPIO pins and log in over a serial console. As a result, provides the easiest & fastest way to get on your Pi. This Pi is about four times faster than the original Raspberry Pi and low cost.
