Simple VME FMC Carrier (SVEC)

Project description

The FMC VME Carrier is an FMC carrier in VME64x format that can hold two FMC cards and an SFP connector. The FMC mezzanine slots use low-pin count (LPC) connectors. This board is optimised for cost and will be usable with most of the FMC cards designed within the OHR project (e.g. ADC cards, Fine Delay).

Other FMC projects and the FMC standard are described in FMC Projects.
