Bluetooth DIP Module - Roving Networks


This is a simple DIP breakout for the Roving Networks Bluetooth® module. Two 0.1" headers allow easy and quick breadboarding. All pertinent pins are broken out and labeled. The module from Roving Networks is powerful, small, and very easy to use. This Bluetooth® module is designed to replace serial cables. The Bluetooth® stack is completely encapsulated. The end user just sees serial characters being transmitted back and forth. Press the 'A' character from a terminal program on your computer and an 'A' will be pushed out the TX pin of the Bluetooth® module. Please note: This module will be replacing the phased-out Mitsumi module. The RN-41 has a lower cost and a more robust AT command set. The shape, size, and pinout of this module is the same as the Mitsumi part, although there are extra pads on the bottom of the device for added functionality.

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 device to a computer.
