The BGM123A256V1 from Silicon Labs is a 2.4GHz blue gecko BGM121 Bluetooth SIP module. It is targeted for applications where ultra small size, reliable high performance RF, low power consumption and easy application development are key requirements. The module fits applications where size is a constraint. The total PCB area required by BGM123 is only 51mm². 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. The module also integrates a high performance, ultra robust antenna which requires minimal PCB, plastic and metal clearance. It is used in wearables, IoT end devices, gateways, health, sports and wellness devices, smart phone, tablet and PC accessories, beacons.
