This is a retired product, but fear not as there is a newer, better version available: WRL-12582
images are CC BY-NC-SA 3.0
Replacement: WRL-10268. The latest revision of this board breaks out the PIO4 pin and has a minor effect on the PCB size. This page is for reference only.
Description: The BlueSMiRF is the latest Bluetooth wireless serial cable replacement from SparkFun 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. We've tested these units successfully over open air at 350ft (106m)!
The remote unit can be powered from 3.3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant. No level shifting is required. 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.
Unit comes without a connector. Please see related male and female pins below.
Note: This is an older rev that doesn't break out the PIO4 pin. We have a few in stock so we're selling them at a reduced price for a limited time. Get them while you can!
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.
