Blue Gecko BGM11S Bluetooth® Module - SiP

The World's Smallest, Fully Certified Bluetooth SiP Module

Silicon Labs’ BGM11S Blue Gecko System-in-Package Bluetooth Module with +3  or +8 dBm TX power, is targeted for applications where ultra-small size, reliable high performance RF, low-power consumption, full modular certification and easy application development are key requirements. At 6.5 x 6.5 x 1.4 mm the BGM11S module fits applications where size is a constraint. BGM11S also integrates a high performance, ultra robust antenna, which requires minimal PCB, plastic and metal clearance. The total PCB area required by BGM11S is only 51 mm². The BGM11S also integrates a Bluetooth 4.2 compliant Bluetooth stack and it can also run end-user applications on-board or alternatively used as a network co-processor over one of the host interfaces. Additionally, the BGM11S has a metal shield enabling full modular certification for WW regulatory compliance.
