Silicon Labs EFR32xG21B 2.4GHz 10dBm Radio Board w/Secure Vault
Silicon Labs EFR32xG21B 2.4GHz 10dBm Radio Boards with Secure Vault features the EFR32xG21 Wireless Gecko Wireless SoC. The Radio Board plugs in directly to the Wireless Starter Kit Mainboard, which features several tools for easy evaluation and development of wireless applications. Silicon Labs EFR32xG21B Radio Board offers an inverted-F PCB antenna (2.4GHz band) and two red and green color LEDs. There are two different +10 dBm Radio Boards. One is for the regular (SLWBR4181B) EFR32xG21A 2.4GHz SoC, and one for the (SLWRB4181C) EFR32xG21B 2.4GHz with a secure vault.
The Wireless Gecko SLWRB4181C wireless radio board plugs into the Main Board provided with the Wireless Gecko Starter Kit. The starter kit includes access to Zigbee® and Thread software stacks. The modular design supports different radio boards, enabling developers to develop Zigbee, Thread, and proprietary wireless applications with the highest level of IoT security provided by Secure Vault.
NOTE: Requires a Wireless Starter Kit Main Board included with any SLWSTK6000x Starter Kit.
