FST-01 with Heat Shrink Tube is a tiny USB 32-bit computer, an abbreviation of “Flying Stone Tiny ZERO-ONE”. “Minimalist Design” is the goal chased during the development. All unnecessary things were cut to make it concise and tidy. Two applications are intended for FST-01. They are Gnuk(the Cryptographic Token for GnuPG) and NeuG(True Random Number Generator based on ADC noise). The board is covered by transparent heat shrink tube. Thus, it is not possible to access SWD port. This can be for daily use, as a Gnuk Token.
