Bluetooth click

Description of product

With the range up to a 100m and low power consumption, Bluetooth click is a great solution if you are looking for a simple way to integrate Bluetooth 2.1 communication to your device. It features the RN-41 low power, class 1 Bluetooth radio module. Bluetooth click communicates with the target board MCU through UART interface and is designed to run on 3.3V power supply only.

RN-41 module

The RN-41 Class 1 Bluetooth radio module delivers up to a 3-Mbps data rate, for distances up to 100 meters (class 1 radio).

Bluetooth 2.1

Bluetooth 2.1 + EDR version includes sniff subrating, a feature that significantly increases battery life for devices that have long periods in idle mode, like home sensor networks, headsets, etc. The host can specify maximum transmit and receive latencies, so that a device knows how often in a cycle it needs to enter sniff mode.
 

Power consumption

The average power consumption in normal mode is 30mA, 8mA in low-power sniff mode, and only 2.5mAin stand-by mode.

Low power consumption and high data rates make this click the best choice in barcode scanners, measurement and monitoring systems, industrial sensors and controls, medical devices, asset tacking, etc.
