We have DE2-115 Educational Board and GPIO-HSTC Daughter Card. We are planning to use GPIO pins available on daughter card for our project, but we are struck at connecnting Board with daughter card. Both DE2-115 and GPIO card have HSMC/HSTC connectors ,as we are trying to connect the casing in coming in between, we think that this is becoz both DE board and GPIO card have female HSMC/HSTC connectors. Can you let us know which connector ( ex. Male to male or female to female) will be helpfull in our case. thanks, raja.
