Kali on Raspberry Pi2 - User Instructions

If all you want to do is install Kali on your Raspberry Pi2, follow these instructions:

1. Get a nice fast 8 GB micro SD card or eMMC.
2. Download the Kali Raspberry Pi2 image from our downloads area.
3. Use the dd utility to image this file to your microSD card. In our example, we use a microSD which is located at /dev/sdb. Change this as needed.

xzcat kali-linux-$version-rpi3-nexmon.img.xz | dd of=/dev/sdb bs=4M

Once the dd operation is complete, boot up the Raspberry Pi2 with the microSD plugged in. Log in to Kali, that’s it, you’re done!
