The Bluetooth Mate Silver is designed specifically to be used with the Arduino Pro, Arduino Pro Mini or LilyPad Arduino. These modems work as a serial (RX/TX) pipe, and are a great wireless replacement for serial cables. Any serial stream from 2400 to 115200 bps can be passed seamlessly from your computer to your target.
Bluetooth Mate Silver is meant to plug directly into an Arduino Pro, Pro Mini, or LilyPad Mainboard. Because the pins are arranged to do this, if instead you want to plug it into an FTDI Basic USB-Serial converter to communicate with a PC, you'll have to swap TX and RX.
The Roving Networks RN-42 is perfect for short-range, battery-powered applications. It uses only 26µA in sleep mode while still being discoverable and connectable. Multiple user-configurable power modes allow you to dial in the lowest power profile for a given application. If you need longer range, check out the Bluetooth Mate Gold which has an RN-41 Class 1 module.
The Bluetooth Mate has on-board voltage regulators, so it can be powered from any 3.3V to 6V DC power supply. Level shifting is all set up so the RX and TX pins on the remote unit are 3-6V DC tolerant. 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's DB9 RS232 port.
Unit comes as shown. Connection pins are not included.
This version of the Bluetooth Mate Silver uses V6.15 firmware, and correctly labels the hardware reset pin on the bottom of the board as PIO4 (previous versions mislabeled this pin). Should you need to reset the Mate, pull this pin High upon power-up, then toggle it three times.
