Introduction

The RNBD451 module is based on Microchip’s PIC32CX-BZ2 Bluetooth^® Low Energy System-on-Chip (SoC) that provides a complete solution to implement Bluetooth 5.2 Low Energy connectivity. These modules are interfaced 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. The host microcontroller can dynamically configure the RNBD451 module with a few simple ASCII commands. The RNBD451 module, combined with Microchip’s Bluetooth Low Energy silicon with necessary GPIO and an on-board PCB antenna, creates an easy-to-use drop-in solution.
