EFR32MG21 Series 2 Modules

MGM210 Zigbee, Thread, Bluetooth and multiprotocol modules feature an optimized low-profile form-factor with either an integrated chip or PCB antenna for space-constrained IoT designs including smart lighting, HVAC, building and factory automation systems. The module is offered in two form factors:

  • The MGM210P comes in a PCB package with a chip antenna. MGM210PB modules support Silicon Labs' enhanced security option, Secure Vault. More information on Silicon Labs' security portfolio can be found here.
  • The MGM210L offers a custom form factor with a PCB trace antenna designed to simplify mounting inside LED bulb housings. The modules are designed to maximize wireless range, operate in higher temperature ratings, and come with extensive global regulatory certifications to deliver the perfect wireless solution for cost-sensitive, high-volume smart LED lightbulbs.

Securing Your IoT Product

IoT security is key to protecting company brands, end-user privacy and commercial viability of products. Vulnerabilities can be exploited through both remote Internet attacks and physical hands-on-attacks.

Developers using the Silicon Labs MGM210P family have access to the highest level of IoT security provided by Secure Vault.
