Introduction

The BGM121/BGM123 Blue Gecko Bluetooth SiP Module family is targeted for applications where ultra-small size, reliable high performance RF, low-power consumption and easy application development are key requirements. At 6.5×6.5×1.4 mm the BGM121/BGM123 module fits applications where size is a constraint. BGM121/BGM123 also integrates a high performance, ultra robust antenna, which requires minimal PCB, plastic and metal clearance. The total PCB area required by BGM121/BGM123 is only 51 mm². The BGM121/BGM123 has Bluetooth, CE, partial FCC, ISED Canada and Japan certifications. Based on the EFR32BG1 SoC, the BGM121/BGM123 also integrates a Bluetooth 4.2 compliant Bluetooth Low Energy and it can also run end-user applications on-board or alternatively used as a network co-processor over one of the host interfaces.
