Hi.

The Basic ESC has two signal cables. One black and one white. I have a PM07 board, but it only wants one cable for signal. Do I just skip the black signal wire and solder the white one only?

Hi @uchiha,

The wire which actually caries the signal is the white one. The black wire is the reference wire, so should be connected to ground 🙂

Is it ok to twist it together with the thicker black wire and solder them together?

Yes, that should be fine 🙂
