Connector Between Flight Controller (FC) and ESC

The Flight controller and the ESC talk together through a particular port, circled below:

Note, the order of the pins on the flight controller WILL ABSOLUTELY be different from the order on the ESC. Getting this wrong and powering up with a smoke stopper WILL destroy your components.

For example, both FC and ESC side of the wire will use an 8 pin connector.

On the FC side, the order of the pins may be: 5V, G, Curr, RX, S1, S2, S3, S4

But on the ESC side, they may be different: G, 5V, TX, Curr, S4, S3, S2, S1

For this reason, I have pre-made the wire connectors so you don’t need to worry about this.

Just make sure before you power up with a battery for the first time, that you have the SMOKE STOPPER plugged in between the battery and the ESC
