I took apart my Eachine Falcons 250 so I can use some of the parts to build another drone. I took the CC3D flight controller from my old drone and want to connect it to a new board. I realized that the CC3d Flight controller have these pins that I used to just plug into my old board. But the new board doesn't have anything for me to plug in the CC3D. What kind of connector do I need? Please advise. thanks!
