Our Mercury PE1 base board is now the Mercury+ PE1 base board - this transformation, however, hasn't required any shape-shifting. At first glance it's the same PCIe base board as before, but it's now offered in 3 different variants: the PE1-200, PE1-300, and PE1-400. The keen-eyed reader will also notice the third 168-pin Hirose connector, which means the board now supports FPGA and SoC modules in the Mercury+ form factor, which have 3 connectors, as well as Mercury modules with 2 connectors. The additional I/Os can be put to use with an FMC high pin-count add-on board, available on the PE1-300, or via two FMC low pin-count connectors, as on the PE1-400.
