Soldering the SPiCboard

On this page, interested students can find all necessary parts for creating their own SPiCboard and the soldering instructions.
Soldering Night
For participants of the Systemnahe Programmierung in C and System-Level Programming, we organize soldering nights at the beginning of each summer term. At these events, the students can solder their SPiCboard under supervision. All parts are provided (including the microcontroller) and do not have to be ordered by themselves.

    • Case

    To transport your SPiCboard safely, different persons designed suitable cases which you can make in the FabLab.
  • Here you can find the instructions for a case of students from the FabLab (in German).
  • In our Gitos are additional versions.
