BGM210L Bluetooth® Lighting Module

Optimal Performance, Security and Reliability for Smart LED Lighting

The BGM210L is a PCB module for Bluetooth connectivity built around the EFR32BG21 Wireless Gecko Series 2 SoC. It is designed and optimized for the unique needs of smart LED lightbulbs.

The module delivers unparalleled RF performance and energy consumption compliance with CA Title 20. It also offers a powerful and energy-efficient MCU core, 1 MB of flash memory to enable future-proofing capability through OTA firmware updates, and a dedicated core for enhanced security features. In addition, its extended temperature rating and form factor make it suitable for enclosed operation in lightbulb housings.

Certified worldwide and supported by robust, industry-proven software and advanced development tools, BGM210L modules are a complete solution to quickly add Bluetooth connectivity to any IoT design.

Also available is the MGM210L Zigbee, and Thread multiprotocol lighting module.
