Overview

The Microchip RN4871-V/RM140 is a compact Bluetooth v5.0 Low Energy (BLE) transceiver module, integrating a BLE stack and an ASCII command interface over UART. It is designed for straightforward implementation of wireless connectivity in various embedded applications. With its on-board profiles and secure AES128 encryption, it facilitates reliable and efficient data transfer.

Why Choose This Part

This module simplifies BLE integration by providing an on-board stack and an easy-to-use ASCII command interface via UART. Its scripting engine allows for hostless operation, reducing the need for an external microcontroller in some applications. The compact 11.5mm x 9mm footprint and low shutdown current of 2.9 uA make it suitable for space-constrained and battery-powered designs.
