Introduction

The RNBD451 module is based on Microchip's PIC32CX-BZ2 Bluetooth Low Energy SoC, providing a complete solution for Bluetooth 5.2 BLE connectivity. These modules interface with Microchip's simple ASCII command set via a 2-wire or 4-wire (flow control) UART interface, facilitating integration into most applications. The host microcontroller can dynamically configure the RNBD451 module using a set of simple ASCII commands. The RNBD451 module combines Microchip's BLE chip, necessary GPIOs, and an onboard PCB antenna to create an easy-to-use embedded solution.
