Littlebee 20A ESC arduino

Thread starter #1
Hello

I was wondering does any one know how to connect the littlebee 20A esc to Arduino. I am not sure which is the signal wire, ground, wire, and vin wire on my esc. I only notice two wires black and white that can connect to Arduino. Any help is greatly appreciated.

Thanks

Brown gnd.
Red 5V
Orange signal.

Note the power connectors are much thicker.

his looks different. I assume the white is signal and black is signal ground. no third wire since it doesn't supply its internally regulated 3.3V power to external electronics

I would check for continuity between thin black wire and input (single with red) black wire.
