DE1-SoC Board Connector Mate Question

Hello,

I am looking for information about a compatible board-to-board mating connector for the DE1-SoC FPGA board. I am simply going to attach it to a board my team is designing and would like the option for both connecting directly and connecting with cables. Can someone please provide me some information about a compatible mate and cables? I see the DE1-SoC board has a 2x20 (40 pin total) GPIO Connector (x2).

Thank you very much!
