HC-08 Bluetooth serial communication module is a new generation of data transmission module based on Bluetooth Specification V4.0 BLE Bluetooth protocol. The wireless working frequency band is 2.4GHz ISM, and the modulation method is GFSK. The large transmitting power of the module is 4dBm, the receiving sensitivity is -93dBm, and it can realize 80m ultra-long-distance communication in an open environment.
 
The module adopts stamp hole packaging method, which can be patched and welded. The size of the module is 26.9mm×13mm×2.2mm, which is very convenient for customers to embed in the application system.
 
The module adopts TI's CC2540 chip, configures 256K Byte space, supports AT commands, and users can change the role (master and slave mode), serial port baud rate, device name and other parameters according to their needs. It is flexible to use.
TXD: Serial port transmission, 3.3V TTL level.
RXD: Serial port receiving, 3.3V TTL level.
CTS: Serial port flow control, not currently supported.
RTS: Serial port flow control, not currently supported.
DC: Emulate and burn the clock pin.
DD: Emulation and programming data pin.
RST: Module reset pin, requires a low level of no less than 5ms for reset.
VCC: Module power supply pin, requires a DC 3.3V power supply, and the power supply current is not less than 100mA. Operating voltage range: 2.0V~3.6V.
GND: Module public ground.
LED: Module indicator output pin, high-level output, please connect a resistor in series when connecting to the LED.
      Before connecting:
      When the host does not record the slave address, it will be on for 100ms per second;
      When the host records the slave address, it lights up for 900ms per second;
      The slave is on for 1 second every 2 seconds.
      After connecting, the LED is always on.
KEY: Input pin, internal pull-down. This pin is connected to a high level for the master to clear the recorded slave address.

1. Description:
This product is a stereo Bluetooth amplifier module. The Bluetooth version is 4.2.
 
2. Features:
1>. The version is 4.2. It can be compatible with all mobile phones and Bluetooth adapters on the market.
      2>. The distance is 15 meters in open space.
      3>. It supports automatically connecting devices that have been paired and playing music automatically.
      4>. F class power amplifier 5W 5W, high power output, over 8002 sound quality.
      5>. It supports USB sound card, no drive, plug and play.
      6>. Good sound quality, suitable for upgrading and refitting the idle sound box and DIY production.
 
3. Instructions:
      1>. Support USB sound card, free drive, plug and play (normal lithium battery power supply situation).
      2>. This product has dual 5W power amplifier circuit. It can not be used in addition to the power amplifier. The output of two amplifiers can not be connected in parallel or connected to the negative electrode, otherwise the power amplifier chip will be damaged.
      3>. There are two 2-8 European and 3-10W speakers respectively, and 3 European 5W and 4 European 10W horn are used. The output is stereo.
      4>. Maximum working current is 5V 2A, using 5V 2A or more voltage power supply, sound quality will be better.
      5>.It is suggested that a 3.7-5V lithium battery (the lithium battery needs a protective plate! It can charge a lithium battery with a USB rechargeable battery, and the USB port can not be used as a power supply port.) or a 5V adapter be used for power supply. It can not use voltage and current unstable power supply, such as dry battery, portable charger, multi-function transformer and so on.
      6>. When the Bluetooth board is installed, the antenna should not be close to the metal parts so as not to affect the transmission distance.
 
4. Operation:
      Start the cell phone Bluetooth, scan the device, find the "DW-CT14 " to click connection.
 
5. Note:
The charging interface of this product is a current limiting charging mode without charge management. For your safety, be sure to use a regular lithium-ion battery with a protective plate, which can cause loss due to improper use.
