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 to 115200 bps can be passed seamlessly from your computer to your target.

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

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.
