BBMagic is a series of small and practical building automation modules that communicate wirelessly via Bluetooth. BBMagic modules are designed by Polish electronics engineers with many years of professional experience and passion. Using the Bluetooth modules of the BBMagic series, designing and building a comprehensive intelligent installation for residential and industrial buildings is a very simple task, both in old and newly commissioned buildings. Thanks to the latest Bluetooth BLE technology, BBMagic modules are characterized by high data transmission speed and significantly reduced power consumption. Thanks to this, these modules can work on one battery for a very long time. This is a particularly important advantage when access to direct power supply from the electrical installation is difficult in the building. BBMagic modules are compatible with single-board minicomputers from the Raspberry Pi series. The manufacturer provides the necessary technical support, which in addition to hardware support also includes software and libraries to facilitate the creation of specific hardware and software applications.
