CBM-003 is a Class 2 embedded Bluetooth module designed to be integrated into LED drivers, different lighting control applications, light fixtures, and LED bulbs. It is pre-programmed with Casambi’s proprietary firmware making it completely compatible with other Casambi enabled devices.

CBM-003 is controlled wirelessly with Casambi smartphone and tablet (“smart device”) applications using Bluetooth protocol. Devices form a self-healing and self-organizing wireless mesh network automatically so that a large number of luminaires can be controlled from any point. No external gateway module is needed.

! The CBM-003A has been discontinued. Please consider using either CBM-003B or CBM-003C instead. CBM-003B comes with an on-board SMD ceramic chip antenna, while CBM-003C features a 1/4 wavelength monopole antenna, both superior to the CBM-003A, which uses a sheet metal PIFA antenna.
