PMC Mezzanine Board Voltage Keying/Coding Pin

PMC Mezzanine Board Voltage Keying/Coding Pin

  • To prevent accidental damage when fitting mezzanine boards, keying/coding pins are bolted to the VMEbus boards to distinguish between 3.3 V and 5 V operation. The mezzanine boards have a hole drilled in the appropriate position. The keying/coding pin thus ensures that only mezzanine boards with the same operating voltage can be inserted. For double‐height euroboards 2 pieces are required.
