Gnukey is a hardware security token. This hardware token uses an STM32F103TB (ARM Cortex M-3 uCU) that can run Gnuk, Neug or u2f-token.
Below is the bill of materials needed for soldering the gnukey pcb. While there is one LED used, the table contains two (one red and one blue). Similarly, for the LED resistor, depending on the resistance more or less current will pass through affecting the brightness.
The bill of materials can be found on Octopart. Additionally, a 1-click-bom is in the root folder of the repository.
As mentioned earlier, the PCB is designed to be used with a case. The case designs can be found at gnukey-ds repo. Below is an image showing how the final Gnukey token will look like using the cases from the gnukey-ds repo.
