some type of a cross between a pmod board and a maker type breakout board would be nice
example I need to attach a n odd ball SOIC-8 chip,to a pmod, or a QFN package
in the maker space they sell breakout boards you can solder a surface mount chip to
example: https://www.amazon.com/Adafruit-Breakout-SOIC-8-MSOP-8-TSSOP-8-6/dp/B00OKCOKVE
you can then mount this to a pmod breadboard (sold by digilent)
it would be nice to have a single board to purchase
2nd suggestion: an lvds pmod - single ende input (4x) lvds output and 4x input
3rd (option a) suggestion: a pmod with level shifters and an sot-23 LDO please not the autosense level shifters that do not work well,
LDO means 3v3input 2v5 out,or 1v8 out
use an 8position dipswitch to set the direction per pin
or a pmod with 4x level shifters and 4x pins to control direction from the fpga
