Cryptostick

Nitrokey Pro PCB Design

Nitrokey Pro is a USB 32-bit computer with STM32F103 processor and an OpenPGP smart card. It has a minimalistic design, the MCU is running at 72MHz, and it has a SWD port for main flash ROM update.

This is Nitrokey PCB design for KiCAD, based on Niibe Yutaka's Flying Stone Tiny 01 (FST-01).
