FMC Mezzanine Ecosystem: Extend Analog and High-Speed I/O with VITA 57
FPGA dev boards never have enough I/O: you need a high-speed ADC, an optical module, or LVDS sensors — and you don't want to redesign the PCB every time. FMC (FPGA Mezzanine Card, VITA 57 standard) solves this: one carrier board + a library of standard mezzanine cards, swap the card to change the interface. This article walks through LPC vs HPC, pin budget, and common mezzanine configurations.
