BGM121A256

The World’s Smallest Bluetooth SiP Module

Silicon Labs’ BGM121A256 SiP Bluetooth Module has +8 dBm TX power and 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 BGM121A256 module fits applications where size is a constraint. BGM121A256 also integrates a high performance, ultra-robust antenna, which requires minimal PCB, plastic and metal clearance. The total PCB area required by BGM121A256 is only 51 mm². The device 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.
