Overview

The RN4870-V/RM140 is a fully integrated Bluetooth Low Energy (BLE) 5.0 module designed to simplify the addition of wireless connectivity to embedded designs. It features an on-board BLE stack and an ASCII command interface over UART, allowing for rapid integration without deep knowledge of the Bluetooth protocol.

Why Choose This Part

This module is pre-certified (FCC, CE, ISED, etc.), which significantly reduces time-to-market and regulatory costs. It features a built-in scripting engine for hostless operation, enabling basic logic without an external microcontroller.

Applications

Serial Cable Replacement
Uses the UART Transparent Service to bridge serial data between two devices over BLE seamlessly.
IoT Sensor Nodes
Ideal for battery-powered sensors using its 60uA sleep current and 1.9V to 3.6V supply range.
Industrial Data Collection
Leverages its small 12mm x 22mm footprint and integrated chip antenna for compact industrial monitors.
Home Automation
Supports up to five public and four private services for controlling smart home appliances and lighting.
