HC06 Bluetooth module 4PIN original version

Shipping list：

Hc-06 Bluetooth board one

Pay special attention to; The following connection methods are incorrect:

The following situations are not product quality problems and are caused by wiring errors, and will not be returned without warranty:

1. self-receiving spontaneous test success, resulting in TXD or RXD with the ground short circuit in use

2. The module is damaged due to reverse power supply

This module is for export, students and electronic enthusiasts to buy this module should first consider clearly, this can not be returned or replaced, do not burn out when the time is said to be our quality problem to return or replace, before shipment all have good test

Product features:

1. The core module uses HC-06 slave module. The output interfaces include VCC,GND,TXD and RXD

2. Led indicates the bluetooth connection status, blinking means no Bluetooth connection, steady on means Bluetooth has been connected and the port is opened

3, baseplate 3.3V LDO, input voltage 3.6-6V, unmatched current about 30mA, about 10mA after pairing, input voltage is prohibited to exceed 7V!

4, interface level 3.3V, can be directly connected to a variety of microcontroller (51, AVR, PIC, ARM, MSP430, etc.), 5V microcontroller can also be directly connected, without MAX232 can not go through MAX232!

5, open effective distance of 10 meters, more than 10 meters is also possible, but do not guarantee the connection quality of this distance

6. After pairing, when the full-duplex serial port is used, there is no need to know any Bluetooth protocol, but it only supports 8-bit data bit, 1-bit stop bit and no parity check communication format, which is also a commonly used communication format, and other formats are not supported.

7. When no Bluetooth connection is established, the baud rate, name and pairing password can be set by AT instruction, and the set parameters can be saved after power failure. Automatically switch to pass-through mode after bluetooth connection

8, small size (3.57cm*1.52cm), factory SMT production, to ensure the quality of SMT. And set transparent heat shrinkable tube, dustproof and beautiful, and has a certain anti-static ability.

9. This link is slave computer, which can pair with all kinds of computers with Bluetooth function, Bluetooth host, most mobile phones with Bluetooth, PDA, PSP and other smart terminals. Slave computer cannot pair with each other.

Facts (very important) :

TXD: sending end, generally expressed as its own sending end, normal communication must be connected to the RXD of another device.

RXD: receiving end, generally expressed as their own receiving end, normal communication must be connected to the TXD of another device.

Normal communication when the TXD itself is always connected to the device RXD!

Self-absorption: Normal communication TXD RXD connect other devices, so if you want to receive their data, as the name implies, is receiving themselves to send data, is directly connected to the RXD TXD itself, that is, used to test whether the sending and receiving of normal itself, is is it is a simple test method, when a problem first do this test to determine whether the product failure. Also known as loop testing.
