When integrating the V1.1 module, developers must pay close attention to the and shielding . Because it is a radio-frequency (RF) component, the physical layout of the surrounding circuitry can significantly impact signal range and stability. Version 1.1 often includes minor refinements in the RF front-end to improve sensitivity compared to the initial V1.0 release.

: Operates within the License-exempt ISM (Industrial, Scientific, and Medical) bands, frequently at 2.4 GHz or sub-GHz ranges depending on regional configuration.

: Designed as a compact, surface-mount module to be easily integrated into larger PCB (Printed Circuit Board) designs.
