SparkFun Bluetooth Modem - BlueSMiRF Silver

The BlueSMiRF Silver is the latest Bluetooth wireless serial cable replacement 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 used in the BlueSMiRF Gold. 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 remote unit can be powered from 3.3 to 6 V for easy battery attachment. All signal pins on the remote unit are 3 to 6 V tolerant. No level shifting is required. Do not attach this device directly to a serial port. You will need an RS-232 to TTL converter circuit if you need to attach this to a computer.

Unit comes without a connector. This is a single unit only. We recommend the purchase a USB dongle to interface to a computer if you do not already have access to a computer with Bluetooth connectivity.
