This past year at DEF CON, the Embedded Systems Village (ESV) sold a custom badge that at the time, I thought was a CTF challenge. Fast forward months later when I’ve actually sat down to look at the badge, It turns out the badge is centered around a “FTDI chip” which enables communication to multiple embedded communication protocols. The badge actually enabled CTF contestants at DEF CON to poke at embedded systems, and is a pretty useful device for the casual hardware hacker.
