Power
Description
The FreeForm/Express S6 is designed to be powered from the PCIe bus. The board requires +3.3V DC for
all circuitry. +12VDC is required for the FMC power good signal and as the FMC module’s power source.
The FreeForm/Express S6 generates all other required power rails on-board.
In addition, a programming / desktop debugging standalone power connector P1 is provided.
WARNING: Do not plug the FreeForm/Express S6 into a PCIe slot with an external power source
connected to P1. This could lead to board damage and void the product warranty.
