Hi! Project author here. The keyboard has both the macro functions (from F1 to F12) and the keylogger. Since it&#x27;s completely open source &#x2F; open hardware you can disable the keylogger in the firmware if you don&#x27;t like it. I personally don&#x27;t use it. No one uses the keyboard except me and I&#x27;m not going to log my own stuff :) . Just put it there to show that it is possible to do it. Regarding the source code, it&#x27;s available in my github: <a href="https:&#x2F;&#x2F;github.com&#x2F;masaleiro&#x2F;HacKeyboard" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;masaleiro&#x2F;HacKeyboard</a>
