Plug-and-play simplicity: No wireless software development is needed, just send commands from any microcontroller (MCU) over UART. It also supports Host Controller Interface (HCI) mode for Linux/MPU applications.

Antenna for tricky situations: RNBD350UE comes with a U.FL connector for external antenna so you can add wireless to applications where a PCB antenna doesn't work.  

Global regulatory certified: RF certification can take a lot of time and money. RNBD350UE modules are pre-certified in US, Canada, Europe, Taiwan, Japan, and Korea. Choosing a pre-certified module bypasses the certification process allowing you to focus on your product.
