This is a plug & play encoder for your Sotion motor. It will fit in either the Sur Ron Ultra Bee or Talaria Sting versions.
The version you select will dictate the plug type that is used to connect to your controller.
NB: the Light Bee is equipped with a Hall Sensor by default and comes with a 6 pin plug. As the encoder requires 7 pins, you have to change connectors on both ends to accommodate the encoder.
