At WUT we're developing Sinara Open Hardware ecosystem and recently received prototypes of the board that may be of interest to you. The project is called Fast Servo and is designed in a 3U form factor to be used in crate or standalone. It features 2ch 125 MSPS 16b ADC and 2ch 125 MSPS 14b DAC and is based on Trenz Xilinx Zynq module. After we're done with testing, it will be available for purchase from our industrial partners.

For more information see project Wiki.

If you are interested in using Fast Servo with linien we can contribute and port it to our board.
