RNBD451PE Series

[Application Examples](https://mplab-discover.microchip.com/v2/category/com.microchip.code.examples/com.microchip.ide.project?dsl=rnbd451) Effortlessly add Bluetooth® Low Energy (LE) 5.2 to your design with our RNBD451PE plug-and-play module. The RNBD451PE is truly plug-and-play – there is no programming, RF-design or regulatory certification required. Part of our [Bluetooth LE product portfolio](https://www.microchip.com/en-us/products/wireless-connectivity/bluetooth-low-energy), the RNBD451PE saves time, money and engineering resources which reduces your time to market. **Plug-and-play simplicity:** No wireless software development needed, just send commands from any MCU over UART. Supports Host Controller Interface (HCI) mode for Linux/MPU applications. **RF-ready with onboard antenna:**RF design is complicated, but with the RNBD451PE module, you don’t have to worry about it. The RNBD451PE module comes with an on-board PCB antenna built for optimal RF performance, saving you time and RF-design hassle. **Global regulatory-certified**: RF certification can take a lot of time and money. RNBD451PE modules are pre-certified in US, Canada, Europe, Taiwan, China, 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) today and get started with creating your own mobile app. **Free personalized design check service**: When you choose our products, we will review and provide guidance on the schematic, PCB layout and RF testing of your wireless.
