  • This page provides technical information about fitlet2 FACET-Cards.
  • FACET-Cards extend fitlet2 functionality and I/O.
  • FACET-Card stands for Function And Connectivity Extension T-Card
  • FACET-Card standard is open to allow 3rd parties to design their own application specific FACET-Cards
  • The full production files of each Compulab FACET-Card are published below to allow 3rd parties to modify for their needs

Mechanical constraints

There are two form-factors of FACET-Cards

Narrow FACET-Card
Wide FACET-Card
  • Narrow occupies the M.2 E-Key slot (leaving the SATA slot native)
  • Wide FACET-Card occupies both M.2 slot (usually requiring SATA slot on the FACET itself)
