Wireless Gecko Series 2 devices are the next evolution of Wireless Gecko devices bringing high performance, low power and secure solutions to the Internet of Things. Designed to increase processing capability, improve RF performance and lower active current, the devices also provide a higher level of security.
EFR32BG21A020F1024IM32-BR devices are 2.4 GHz wireless SOCs optimized for line-powered Bluetooth Low Energy and Bluetooth mesh applications, including connected lighting, smart plugs, gateways and voice assistants. An 80 MHz ARM® Cortex®-M33 core provides plenty of processing capability while a dedicated security core provides faster encryption, secure boot loading and debug access control. With better than -104 sensitivity for Bluetooth Long Range and up to +20 dBm output power, EFR32BG21A020F1024IM32-BR devices provide a robust RF link to ensure reliable communications. Series 2 uses the same tools as Series 1, providing easy migration and fast time-to-market with development kits, SDKs, mobile apps and our patented network analyzer.
