Kali is a great tool for testing the security of your network & the operating system works on just about everything that can run Linux. That includes the Raspberry Pi. What's even better is a new distribution that brings along support for a touchscreen. The special distribution is built for 2.8 touch screens. This means you'll find a special GUI interface built for touch & the small screen. It's likely a little clunky & hard to use, but the pocket-sized nature of it means you can keep it around without wasting a lot of space. Head over to Offensive Security to grab a copy of the distribution. You can read about this on https://www.offensive-security.com/kali-linux/kali-with-raspberry-pi-tft-support/. Although slightly on the expensive side – especially compared to the Raspberry Pi itself – a small functional touch screen that can do a whopping 320×240 resolution can be extremely useful at times. We used it in one of our hardware projects & implemented a couple of Desktop shortcuts that would “start” & “stop” our automated tool, giving us both an input & output source. Due to the nature of the patches & image configuration, we had to build a separate image for the TFT Kali Raspberry Pi image. However, our build script for this image can easily be modified to accommodate any changes you may require. As with all our custom Kali Linux ARM images, we can find the source of the build script in our Offsec github page.
