RN-4678-PICTAIL

RN4678 Bluetooth® 4.2 Dual-Mode Module The Easy-to-Use, Flexible Solution for BLE and Bluetooth Classic Connectivity Summary The RN4678 is a fully certified Bluetooth® 4.2 Dual-Mode Module which enables you to easily add classic Bluetooth and Bluetooth Low Energy (BLE) capability to your products. Delivering local connectivity for the Internet of Things (IoT), the RN4678 bridges the end application to smartphones and tablets for convenient data transfer, control and access to cloud applications. This Bluetooth SIG-certified module provides a complete wireless solution with Bluetooth stack on board, integrated antenna and worldwide radio certifications in a compact surface-mount 22 × 12 × 2.4 mm package. It supports GAP, SDP, SPP and GATT profiles. Data is transferred over the Bluetooth link by sending/receiving data via transparent UART mode, making it easy to integrate with any processor or microcontroller with a UART interface. Configuration is made easy through ASCII commands via UART. The RN4678 enables rapid product development and faster time to market, and is designed to provide designers with: ■ Simple integration and programming ■ Reduced development time ■ Interoperability with Bluetooth host ■ Wide range of applications The RN4678 is a complete and fully-certified module with integrated ceramic chip antenna and RF shield. The RN4678U is a low-cost alternative with RF pad (for external antenna) and no RF shield. Low-power usage and flexible power management maximize the lifetime of both the RN4678 and RN4678U module in battery-operated devices.
