Microchip Technology RNBD451 BLUETOOTH® Low Energy Module

Microchip Technology RNBD451 BLUETOOTH® Low Energy Module utilizes the PIC32CX-BZ2 BLUETOOTH Low Energy System-on-Chip (SoC) to implement BLUETOOTH 5.2 Low Energy connectivity. The RNBD451 is connected through a two- or four-wire UART interface with a simple ASCII command set for easy integration into most applications.

The Microchip RNBD451 Module is dynamically configured by the host microcontroller using a few simple ASCII commands. The RNBD451 incorporates BLUETOOTH Low Energy silicon with the required GPIO and an onboard PCB antenna to create an easy-to-use drop-in solution.
