USB armory - The open source compact secure computer
USB armory Mk II debug accessory ================================
The USB armory is an open source hardware design, implementing a flash drive sized computer.
The USB armory Mk II exposes a USB Type-C receptacle, which allows through the so called USB-C 'debug accessory mode' to route analog/debug signals over its connector, the USB armory Mk II design leverages on this to break out UART, SPI, I²C, CAN (pre-transceiver), GPIOs connections to/from its application processor.
