What are the key features of RN41-I/RM?

Class 1 Bluetooth 2.1+EDR with up to 100 m wireless range for robust industrial and automation links
Fully integrated Bluetooth stack and firmware on 3.3 V supply, eliminating the need for a separate host protocol stack
Compact 35-pin SMD module (microelectronic assembly) with embedded antenna for fast OEM integration

What is RN41-I/RM used for?

The RN41-I/RM suits industrial automation, medical telemetry, and portable data-logging devices that require a certified Class 1 Bluetooth link over distances up to 100 m. Its 3.3 V supply range and self-contained protocol stack allow engineers to add wire-replacement wireless connectivity without developing proprietary RF firmware. The module is also used in point-of-sale peripherals, barcode scanners, and wireless HID accessories where reliable Bluetooth 2.1+EDR performance is needed.

Frequently Asked Questions

What Bluetooth version and wireless range does the RN41-I/RM support?

The RN41-I/RM implements Bluetooth 2.1+EDR (Enhanced Data Rate) as a Class 1 module, achieving wireless ranges up to 100 m in open-air conditions. The Enhanced Data Rate mode supports data throughput up to 3 Mbps, making it suitable for applications requiring both range and speed, such as industrial sensor gateways and portable medical monitors.

What supply voltage does RN41-I/RM require, and is it compatible with 3.3 V microcontroller systems?

RN41-I/RM operates from a 3.0 V to 3.6 V supply, with a nominal voltage of 3.3 V. This makes it directly compatible with 3.3 V MCU platforms without the need for level shifting on the UART or GPIO interface lines, simplifying integration into designs using common 3.3 V microcontrollers and minimizing BOM complexity.

How does the RN41-I/RM simplify Bluetooth integration compared to a standalone radio IC?

Unlike a bare Bluetooth radio IC, the RN41-I/RM includes the complete Bluetooth stack, firmware, embedded antenna, and RF matching network in a single 35-pin SMD module. Engineers can communicate with it over a UART interface using simple ASCII commands, bypassing the need to develop or port a Bluetooth protocol stack and reducing time-to-market by weeks.

Is RN41-I/RM suitable for use in medical monitoring wearables with tight board space constraints?

Yes. The RN41-I/RM is packaged as a compact microelectronic assembly module with a surface-mount footprint, allowing it to fit on small PCBs typical of wearable medical devices. Operating at 3.3 V and supporting Class 1 Bluetooth 2.1+EDR at up to 100 m range, it provides a reliable wireless link for continuous biometric data transmission from body-worn sensors to a host device.
