It's effortless to add Bluetooth® LE to your design with our RNBD451PE plug-and-play module. The RNBD451PE is truly plug-and-play; it requires no programming, RF-design or regulatory certification. Part of our Bluetooth product portfolio, the RNBD451 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.
