Overview

The RN4678-V/RM100 is a fully certified Bluetooth v5.0 Dual-Mode module that supports both Bluetooth Classic (BR/EDR) and Bluetooth Low Energy (BLE) communication. It features a built-in Bluetooth stack, integrated chip antenna, and a transparent UART mode that simplifies serial data transfers without requiring complex protocol knowledge.

Why Choose This Part

The module provides a seamless migration path by supporting both Classic and BLE protocols simultaneously, which is essential for broad smartphone compatibility. It reduces development time significantly through its ASCII command interface and integrated regulatory certifications (FCC, IC, CE).

Applications

Dual-Mode Data Bridges
Connecting legacy Bluetooth Classic devices to modern BLE-enabled mobile applications via the Serial Port Profile (SPP) and GATT.
Industrial Serial Replacements
Replacing physical RS-232 or UART cables with a wireless link in industrial automation and monitoring systems.
IoT Sensor Hubs
Collecting data from low-power BLE sensors and relaying it to a central controller or mobile interface.
Handheld Medical Devices
Providing reliable wireless data logging for portable diagnostic tools that require compatibility with a wide range of host devices.
