    6.Note

    The module antenna can not be surrounded by other objects, especially metal devices, otherwise it will seriously affect the communication distance;

    When using the communication module, to avoid damage to the components caused by the static electricity of the human body and cause component failure, it is recommended to wear an anti-static wrist strap during use.
