The BlueSMiRF is the latest Bluetooth wireless serial cable replacement from Spark Fun Electronics. These modems work as a serial (RX/TX) pipe. Any serial stream from 9600 to 115200bps can be passed seamlessly from your computer to your target. Spark Fun Electronics even tested these units successfully over open air at 350ft (106m !!!). The remote unit can be powered from 3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant. No level shifting is required.
