For the 64-Bit OS support we need to use Raspberry Pi 4
I’m using Raspberry Pi 4 Model-B With * Gigs of RAM, A 4GB RAM model would work just fine.

But First what is Raspberry Pi and what is it used for ?

he Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse.
It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python.
It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games.

What’s more, the Raspberry Pi has the ability to interact with the outside world, and has been used in a wide array of digital maker projects, from music machines and parent detectors to weather stations and tweeting birdhouses with infra-red cameras.
We want to see the Raspberry Pi being used by kids all over the world to learn to program and understand how computers work.

• Step 1

Assemble and enclose the Raspberry Pi, We recommend a case with passive cooling or with a small fan and heat-sinks.
Yes of course you can the Pi without any case or cooling setup, But we recommend to use a cooling case for protection and better performance.

• Step 2

Download Kali-Linux Image from the official website.
You can get the download link from the below URL.
You need to select ARM image category, then choose the Raspberry Pi 64-bit Image.

• Step 3

Now you need to write this image to a Micro SD card, Which you are going to use it on your Raspberry Pi.
You can use either Balena Etcher or the official Raspberry Pi imager for this task.

Here we are using the official Raspberry Pi imager. You can download the imager from the following URL.
https://www.raspberrypi.com/software/
Here is the download link for Windows machines
https://downloads.raspberrypi.org/imager/imager_1.6.2.exe

• Step 4

Write Kali-Linux image to the Micro SD-Card. Please follow the following images.

1, Launch the Pi Imager and select Choose OS.

2, Select the option “Use Custome” for our Kali-Linux Image

3, Browse and choose the Kali-Linux Image we have downloaded from our PC.

4, Now select storage and choose our micro SD-Card and click write to write the Image.

Note: Please make sure you have selected the correct storage, In our case the SD-Card. If you choose the wrong location the imager will wipe the selected storage location.

• step 5
  Insert the Micro SD-card to your Raspberry Pi. Plug in your Raspberry Pi Power-Brick to the device and
  connect your Pi to a monitor, also plugin your Mouse and Keyboard as well, Then power-on the power brick.

It will take some time for the initial bootup, Wait for it. If everything is perfect your Raspberry Pi will boot into Kali-Linux.

That’s it, Have fun.
