1.1 Tips (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 the most simple test method is the fastest, when problems arise first do this test to determine whether the product failure. Also known as loop testing.
1.2 Level logic:
TTL level: usually the data is expressed in binary. It is specified that 5V is equivalent to logic "1" and 0V is equivalent to logic "0". It is called TTL signal system and positive logic
RS232 level: adopt -12V to -3V, equivalent to logic "0", 3V to 12V logic level, equivalent to logic "1", is negative logic
1.3 Product Features:
1, the core module uses HC-05 from the module, the output interface includes VCC,GND,TXD,RXD,KEY pin, Bluetooth connection status pin (STATE), the output is low if not connected, the output is high after connected
2. Led indicates the Bluetooth connection status. Quick blinking means no Bluetooth connection; slow blinking means AT mode; double blinking means Bluetooth is connected and the port is opened
The bottom plate is equipped with anti-reverse connection diode, with 3.3V LDO, the input voltage is 3.6-6V, the unpaired current is about 30mA, the paired current is about 10mA, the 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 (power CLASS is CLASS 2), more than 10 meters is also possible, but the connection quality of this distance is not guaranteed
6. After pairing, when the full-duplex serial port is used, there is no need to know any Bluetooth protocol. It supports 8-bit data bit, 1-bit stop bit and parity check communication format, which is also the most commonly used communication format, and other formats are not supported.
7. You can enter the AT command mode by raising 34 feet to set parameters and query information
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. Switch to host or slave mode by using THE AT command, and connect to the specified device by using the AT command
10, support from 4800bps to 1382400bps between standard baud rate
1.4 Product Usage:
After pairing, the serial port can be used as a fixed baud rate serial port. Therefore, as long as the serial port device is in the communication format of "fixed baud rate, 8 data bits, no parity check", it can directly replace the original wired serial port without modifying the program. Such as data acquisition, intelligent car, serial printer, outdoor dot matrix strip screen control, etc.
Pair with computer: suitable for computer and device to communicate through bluetooth serial port, the use method is the same as serial port
Pairing with mobile phone: suitable for communication between mobile phone and device through Bluetooth serial port, the use method is the same as serial port
Pairing with Bluetooth host: it is suitable for two devices to communicate directly through Bluetooth serial port, such as between single chip microcomputer and single chip microcomputer, wired serial port and single chip microcomputer, etc. The use method is the same as serial port
Flexible use:
Baud rate conversion, because the receiving end and the sending end can choose their own baud rate, in the case of small data volume can be used as baud rate conversion equipment.
2.1 How to connect bluetooth module to computer (effective in slave mode)
Here is an example of pairing it with a Bluetooth computer:
First, power on the Bluetooth passthrough module, and then the LED flashes. Open "My Bluetooth Location" and click "Search for devices in the valid range".
The system searches for bluetooth devices with the default device name "linvor" (modified name if modified, such as "jiayuanelectron"), double click or right click and choose "add bluetooth device".
Enter the pairing password (default: 1234),
Click "Next". If the password is correct, the connection between the computer and the passthrough module will be established. If bluetooth serial port device has not been installed before, the system will automatically install the driver and generate a virtual serial port
Click Config, select the appropriate COM port,
I can only choose COM5 here, which is the serial port for computer operation after connection. For example, WHEN I open com5 here, the LED of Bluetooth module will change from quick flash to double flash. At this time, you only need to use bluetooth module as the serial port of fixed baud rate of computer, but it is wireless.
Tips:
1. The supply voltage must be 5V, not 3.3V
2. Do not connect the pin of the power cable to the data cable. Confirm it carefully before connecting the cable
3. The LED must enter the slow blinking mode before the AT command test
 
4. After each AT instruction is input, you must press enter to send it
5. If OK cannot be returned, swap RXD and TXD
6. Do not tear the heat shrinkable tube or weld it by yourself. Otherwise, the warranty and return and replacement service will be waived

Support the latest 64-bit raspberry pie 3B, has been tested, please rest assured to buy! . . .
Integrated infrared receiving function Teaching:Expansion board and raspberry pie 3 generations, 2 generations are no welding, can be used directlyThis is a dedicated HIFI Digi expansion board (PiFi Digi ) for the Raspberry 2 B-type, B / A design using Wolfson's high-end digital chip (WM8804G), using the I2S interface, a non-USB interface; After the board, users can set up their own network HIFI player with the audio playback system (such as volumio, xbmc system, etc.). The expansion board provides optical fiber (S / PDIF) and coaxial (RCA) two output interfaces to facilitate external amplifier and other equipment. With it you can get rid of PC power consumption, power on slow, power supply noise and so troubled. . . . Features:1. Digital chip using Wolfson's high-endOf the WM8804GChip, with I2S interface; support for 16 to 24-bit audio data format; distortion and dynamic are very good to support the high 192kHz sampling rate, advanced technology can shake down the inherent jitter (Intrinsic period jitter) control within 50ps RMS , High degree of reduction.\
2. Output port using optical fiber and coaxial two kinds of interface output, user-friendly external amplifier
3. Support hardware mode control volume (I2C interface)\
4. Power supply using raspberry power supply, no external power supply; and the use of π-type filter power supply design, effectively reduce the power supply interference
5.I2S interface with direct digital output, high degree of reduction, non-USB interface, DAC mode, not taking up other extended raspberry raspberry\
6. Power indicator light, easy to observe the expansion board status
7. PCB board on the high gold-plated process, arc traces (high-end HIFI DAC are used arc traces), the better to ensure signal continuity of the impedance and reduce the signal reflection and refraction.\
8. Good sound depends on the real material, fiber optic interface using imported HIFI-class high-quality fiber optic cable, coaxial interface is used Pluse imported audio isolation transformer in providing good digital audio at the same time very good to protect your audio equipment and boards . . . (Similar foreign products have been removed in order to cost, in order to sound a good reliability in order we will not begrudge the cost, not jerry)
9. Integrated infrared receiver, in the absence of network, more convenient to control playback.\
Volumio software parameters:
