Current sensor for the TBS CORE. This is the 100A version. It's compatible with other OSDs as well although we can't take responsibility for that.
The current sensor comes with NO CONNECTORS! There are just plain solder pads and you can solder on your own connectors of choice. We suggest to solder on the ESC leads directly without connectors.
Wire the current sensor between your battery plug and ESC. Please be careful to install it in the right direction, copy below image carefully. When pulling a lot of power, spread some solder to fill up the holes.
