So, what's the difference between the Raspberry Pi Zero and the Zero W? The W in Zero W stands for Wireless, which means that the Zero W module has wireless capabilities. This is the biggest difference between these two similar modules.

Let's take a closer look.
Main differences between Pi Zero and Pi Zero W
The goal of the Raspberry Pi Zero is to provide as much functionality as possible in half the size of an A+ board.
While the Raspberry Pi Zero W was introduced later to support wireless, it can use Bluetooth and Wi-Fi without any additional components and modules.
This is the key difference between the two, the rest of the specs remain the same.

So, if you need the following functionality:
1. 802.11 b/g/n wireless network port
2. Bluetooth 4.1
3. Bluetooth Low Energy (BLE)
4. Raspberry Pi Zero W will be your best choice.
Additionally, the Raspberry Pi Zero W is available in a pinned version called "Raspberry Pi Zero WH"
Raspberry Pi Zero and Zero W Specifications

Raspberry Pi Zero W
The specs of the Raspberry Pi Zero and Zero W are almost identical.
They both have a 1 GHz single-core CPU and 512 MB of RAM. As for the interface, a mini HDMI interface supports micro USB OTG, micro USB power supply and a CSI camera interface (for inserting a camera module).
These boards will provide something called HAT (Hardware Attached on Top) compatible 40 pins. But in general, there are no pins that allow you to easily plug into the interface.
You can choose to use a variety of Raspberry Pi compatible systems according to your functional needs, but in either case, I still recommend you to use the Raspberry Pi OS.
Is the Raspberry Pi Zero series worth buying?

Raspberry Pi Zero
The Raspberry Pi Zero is a popular form of microcontroller, and even if you have many alternatives to the Raspberry Pi Zero, the Raspberry Pi Zero is still the most recommended choice.
Unless of course you have special needs.
In addition to the size of the board, pricing, power requirements, and computing power are also the main highlights of the board.
So if you're looking for a basic microcontroller on a budget, the Raspberry Pi Zero is just for you.
