Hi friend, the connector is HX2.54 Male . Hope this can help you. Regards Carina Reply Your previous message I purchased Chitu MOS Expansion module and Chitu mainboard (Alunar HB-R100 3d printer contains) Please help identify white connector 2-pin model? (JST? or other brand? male/female connector?) ************************************************ NOTE IT IS MY OPINION THAT THE ABOVE MENTIONED HX2.54 IS A TYPO IT SHOULD BE XH2.54 - THE CONNECTOR/HEADER MOUNTED TO THE PCB IS MALE THE CONNECTOR/PLUG WITH WIRES ATTACHED IS FEMALE HOWEVER - MAKE SURE THE VENDOR SHOWS A PHOTO AS IT COULD BE LISTED OPPOSITE??????????
