Recommended Posts

Thank you all for the incredible feedback on the Key Croc. We knew in development that we were on to something game changing, so to hear the enthusiasm from you all directly is truly rewarding. The amount of creativity shown in such a short period of time since initial release is encouraging.

We hope that with this beta release of Key Croc firmware 1.3 we can further that creativity. As always we welcome your feedback here on the forums and of course on our Discord #beta-testing channel.

Thanks for your support and happy hacking!

And an especial big thank you to our team – @Korben for his work on this firmware with the support of @Foxtrot and everyone including 0xdade for feature inspiration.
