Introduction

The RNBD350 module is based on Microchip’s PIC32CX-BZ3 Bluetooth® Low Energy System-on-Chip (SoC) that provides a complete solution to implement Bluetooth 5.2 Low Energy connectivity. The module is interfaced with a host MCU or MPU via a Two-Wire or Four-Wire (Flow Control) UART interface with Microchip’s simple ASCII command set for easy integration into most of the applications. In addition, it supports an 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 a standardized Bluetooth HCI mode. The RNBD350 module, combined with Microchip’s Bluetooth Low Energy silicon with necessary GPIO and an on-board PCB antenna, creates an easy-to-use turnkey solution.
