Product Description

The Bluetooth UART RS232 serial Converter Module can easily transfer the UART data through the wireless Bluetooth, without complex PCB layout or deep knowledge in the Bluetooth software stack, you can combine this bluetooth module with your system:

* MCU, ARM or DSP systems.
* SOC systems.
* Personal Digital Assistants (PDAs)
* Computer Accessories
* Other systems your want to use under bluetooth functions.

[Hardware]

Tips:

TXD: sender, usually expressed as its sender, then another when normal communications equipment RXD.

RXD: Receive-side, generally expressed as their receiver, then another when normal communications equipment TXD
.When normal communications will always take their devices TXD RXD!
Spontaneous self-closing: As the name suggests, is to receive its own transmitted data is received their own TXD RXD, used to send and receive test itself is normal. Also known as loop-back test.

The module has been integrated MAX3232 serial conversion circuit, and with a two DB9 male and one female head, no matter what your equipment is male or female can be connected with the module, the Bluetooth pairing can not respond to AT commands, paired then as a transparent serial transmission of data, the module requires an external power supply, a 3.3V module integrated LDO, the power from the module's power input TTL interface, TTL interface, TXD, RXD for the HC06 module's serial port directly to the output, when the module can not be set higher than 115200bps reset via DB9 connectors, you can use USB to serial interface to re-set by the lower baud rate.
