Silicon Labs’ BGM121 and BGM123 Blue Gecko Bluetooth SiP modules have +8 dBm and +3 dBm TX power, respectively, and are targeted for applications where ultra-small size, reliable high performance RF, low power consumption, and easy application development are key requirements. At 6.5 mm x 6.5 mm x 1.4 mm, the BGM121 and BGM123 modules fit applications where size is a constraint. They also integrate high performance, ultra-robust antennas, which require minimal PCB, plastic, and metal clearance. The total PCB area required is only 51 mm². The BGM121 and BGM123 also integrate a Bluetooth 4.2 compliant Bluetooth stack and they can run end-user applications on-board or alternatively can be used as a network co-processor over one of the host interfaces.

BGM11S modules offer the additional benefit of full Modular FCC, ISEDC, and South Korean certifications, enabling even faster time-to-market.
