The BlueSMiRF is an easy-to-use Bluetooth serial link that works over a range of logic voltages from 3.3 V to 6 V. It has a transmission distance of up to 18 meters. The board carries the RN-42 Class 2 Bluetooth module from Roving Networks, which is a robust, FCC-approved Bluetooth module. A single 0.1″ header for all the pins makes it easy to use with standard solderless breadboards and 0.1″ perfboards.

Overview

The BlueSMiRF Silver is a Bluetooth wireless serial link from SparkFun Electronics. This version of the popular BlueSMiRF uses the RN-42 module, which has a bit less range than the RN-41 module. These modems work as a serial (RX/TX) pipe. Any serial stream from 2400 bps to 115200 bps can be passed seamlessly from your computer to your target.

The modem can be powered from 3.3 V to 6 V for easy battery attachment. All signal pins are 3 V to 6 V tolerant. No level shifting is required.

For more information and resources to help you use the BlueSMiRF Silver, see the guide on SparkFun’s site. The RN-42 Bluetooth module datasheet and the Roving Networks Blueooth product user’s guide can be found under the Resources tab.

Warning: Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit if you need to attach this to a computer.

This unit does not include any additional hardware or connectors. The 0.1″-spaced holes work well with our breakaway male header pins.
