Raspberry Pi 4 2GB RAM With Casing in Pakistan

The Raspberry Pi 3 Model B is the third generation Raspberry Pi. Built on the latest Broadcom 2837 ARMv8 64bit processor the new generation Raspberry Pi 3 Model B is faster and more powerful than its predecessors.

Raspberry Pi Zero-W V1.3 Development Board is the latest version of Raspberry Pi Zero W (Wireless), if you are looking for this, get it here. Zero-W V1.3 Development Board is a super cheap single-board computer. You get a working computer, it is cheaper than any Arduino controller board with a 32-bit processor, and it comes with WiFi and Bluetooth ready.
Though is not a working computer yet, 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 work, 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.
With BCM 2835 (32-bit ARM-based processor) SoC running at 1GHz, the raspberry pi zero is faster than 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.
Yes, it is really attractive, but do bear in mind that you need additional accessories to get it running. At least a USB adapter and microSD card is a must.
