With appropriate header connectors.. Those typically have a "plastic shell" or housing and come with multiple crimp pins that you would crimp onto the wire as needed..
You can buy them precrimped too at various electronic supply/hobby electronic sites,etc..
nope.,not about wires. I asked about the connections like ESCs, LiPo battery and flysky receiver connections to flight controller kk2.1.5. I have headers and connectors but don't the exact connections from where to where?
