This is super cheap single board computer. Hey! you get a working computer, it is cheaper than any Arduino controller board with 32-bit processor, and it comes with WiFi and Bluetooth ready. Though is not a working computer yet, but at least you have the motherboard :) The new Raspberry Pi Zero W offers all the benefits of the Pi Zero v1.3, but with one big difference – built-in Wireless (WiFi and Bluetooth)! More specifically, this giant upgrade is the addition of a BCM43143 WiFi chip BUILT-IN to your Raspberry Pi Zero – just like the Pi 3! No more pesky WiFi adapters - this Pi is WiFi ready. There’s also Bluetooth Low Energy (BLE) on board making the Pi an excellent IoT solution (BLE support is still in the works, software-wise).

Raspberry Pi Zero W is a super-compact, hackable, and ultra-low cost computer, This is the version with built-in WiFi and Bluetooth.

And there is no so call clone version of this super low cost computer, this is the original Raspberry Pi Zero W from Raspberrypi.org, do check the re-seller list under Raspberry Pi Zero W page.

With BCM 2835 (32-bit ARM based processor) SoC running at 1GHz, the raspberry pi zero is faster that Raspberry Pi 1. With mini-HDMI, micro-B OTG USB, and the same 40-pin GPIO it still has great connectivity although you'll probably need some accessories to help you hook it up to your existing devices.

The best part about all this is that the Pi Zero W keeps the same shape, connectors, and mounting holes as the Pi Zero v1.3. 99% of cases and accessories will still be fully compatible with both the Pi Zero W and v1.3 - though if you have a case with a metal top there might be some WiFi chip difficulties.

As many of you know, the Raspberry Pi Zero W alone is not really useful, you need additional accessories to get it running :) At least USB adapter and microSD card is a must. So we recommend this starter kit with:

1 x Raspberry Pi Zero W
1 x Acrylic Case for Rpi Zero/Zero W to protect the Raspberry Pi Zero W
1 x 8GB microSD card with SD card adapter (Rated at class 10)
1 x 5V 2.5A USB Adapter to power it
1 x Raspberry Pi Wire Kit:
- 1 x HDMI mini to standard HDMI adapter/converter
- 1 x USB OTG cable (USB MicroB to to USB Type A receptor)
- 1 x 2x20 Header pin (For GPIO)
