**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.
**Free mobile app and source code for Android™****and iOS****®****:** [Download the app and source code](https://www.microchip.com/en-us/products/wireless-connectivity/bluetooth-low-energy#mobile-apps) to get started with creating your own mobile app.
**Free personalized** [**design check service**](https://www.microchip.com/en-us/support/design-help/design-check-services): When you choose our products, we will review and provide guidance on your schematic, PCB layout and RF testing of your design.
