FST-01 without Enclosure

FST-01 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).   This is a bare board for evaluation, development or those who want their own enclosures.  You can access SWD port and change the content of flash ROM.   Features

• Dimensions: 1.62 x 0.52 inch (including USB plug) 
• USB Bus Powered 
• MCU: 32-bit ARM Cortex M3 at 72MHz (STM32F103TBU6), flash ROM: 128KB, RAM: 20KB 
• SPI Flash Memory: 4MB 
• SWD port, Two I/O pins 
• Content of Flash ROM of MCU: As a side effect of test plan, FST-01 comes with Gnuk version 1.0.1 installed on the flash ROM of MCU and it is protected. You need to disable the protection before writing the flash ROM.
