DevKit General Purpose I/O question

Hi everyone, I need a FPGA dev kit to parallel read/write data to a external ASIC device at ~ 200MB/s. Unfortunately the device I/O is at 1.2V supply, the number of the parallel I/O is 10 ...

Normally I would choose the devkit based on the feature and capabilities instead of finding a board that have 10 IOs @1.2V

Reason would be that most of the devkit kinda expansive, so I would choose one with features I want such as PCIe or ethernets. Then most of them will have HSMC connector for (IO direct out of the FPGA) and those are 2.5V only.

I would suggest the IO expansion or use a voltage divider.
