Instructions

The RNBD350PE-I100 is a plug-and-play Bluetooth low power module that does not require programming, RF design or regulatory certification. The RNBD350PE Bluetooth ® Low Power module provides a complete solution for implementing Bluetooth 5.2 low power connectivity. The module connects to the host MCU or MPU via a two - or four-wire (flow control) UART interface and features Microchip's simple ASCII command set for easy integration into most applications. In addition, it supports HCI mode for seamless integration with Linux-based host processors. The host can dynamically configure the RNBD350 module with a few simple ASCII commands, or switch to standardized Bluetooth HCI mode. The RNBD350 module is combined with Microchip's Bluetooth low-power silicon (with the necessary GPIO and onboard PCB antenna) to form a turnkey solution that is easy to use.
