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.
- 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.
