  • Nice basic module

    posted by Henkies on 06/20/2011

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week


    - You can get started with this module very fast; just apply power and it works immediately

    - Small size (13 x 27 mm)


    - Too bad that it can't be used as master

    - Range is only ± 5 meters


    Connections (pad with golden dot next to it is pin 1):

    1: TX (data out)

    2: RX (data in)

    11: RESET (connect to ground to reset, pullup-resistor of 10K recommended)

    12: VCC (3.3V)

    13: GND

    24: LED output (ON when there is a connection, BLINKS when there isn't).


    Perfect module for applications where you only need simple plug&play BT slave.
