The SMAS PMC -  PCI Carrier Board is designed to hold one PMC (PCI Mezzanine Module - IEEE P1386) compatible board. The carrier board is based upon the Intel 21152-AB 32 bit / 33 MHz PCI bridge. The bridge complies with PCI ver 2.2 specifications. The carrier board supports both ATX based motherboards (motherboard with 3.3V power supply) as well as non-ATX based motherboards.  The onboard DC/DC converter is capable of delivering sustained 5A 3.3V power to the PMC card.
