Looking for a convenient way to replace your serial cable with a high-speed wireless solution? BLUETOOTH to the rescue! Move those bits wirelessly from your Bluetooth host to any device with the BlueSMiRF Gold!


Description [Hide]

Darn cables - they get wrapped up in the wheels. Cats chew through them (I miss poor Fluffy). They make the Roomba's life miserable.

Ahhh! The BlueSMiRF Gold by Sparkfun uses a new Bluetooth module by Roving Networks to create a cool virtual cable that can stream serial data from 2400 to 115200bps, working as a serial (RX/TX) pipe. They've even been tested successfully over a distance of 106M (350ft) in open air. Just try to trip over that cable. I dares ya!

Many people are using modules like this for on-the-fly programming and debugging of mobile devices (robots, remote sensors, embedded systems tucked deep into places where you can't reach...). Compared to having to fetch your sumo robot, plug it in, load code, then reposition it for another battle, a Bluetooth solution makes it as easy as tweaking a variable, and hitting the "send" key!

This unit can take power from a 3.3V to 6V supply, and all signal pins are suitably 3V-6V tolerant, not needing any shift-leveling.

NOTE: Do not attach this device directly to a serial port. RS232-to-TTL conversion is required before hooking it directly to your computer.

Dimensions: 42x16.5x5.6mm

Features:

  •     FCC Approved Class 1 Bluetooth Radio Modem
  •     Extremely small radio - 0.15x0.6x1.9"
  •     Very robust link both in integrity and transmission distance (100m) - no more buffer overruns!
  •     Low power consumption : 25mA avg
  •     Hardy frequency hopping scheme - operates in harsh RF environments like WiFi, 802.11g, and Zigbee
  •     Encrypted connection
  •     Frequency: 2.4~2.524 GHz
  •     Operating Voltage: 3.3V-6V
  •     Serial communications: 2400-115200bps
  •     Operating Temperature: -40 ~ +70C
  •     Built-in antenna

Remember, you'll have to have your own Bluetooth-enabled host device, or have a Bluetooth USB dongle to attached to your PC!
