Nice basic module – Wireless Bluetooth RS232 TTL Transceiver Module Reviews

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.
