Blue Gecko BGM123 Bluetooth® Module - SiP

The World’s Smallest Bluetooth SiP Module

Silicon Labs’ BGM123 Blue Gecko SiP Bluetooth Module has +3 dBm TX power is targeted for applications where ultra-small size, reliable high performance RF, low-power consumption and easy application development are key requirements. At 6.5 x 6.5 x 1.4 mm the BGM121 module fits applications where size is a constraint. BGM123 also integrates a high performance, ultra robust antenna, which requires minimal PCB, plastic and metal clearance. The total PCB area required by BGM123 is only 51 mm². The BGM123 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.
