Specification
|
1
|
This module is a radio-sensitive device, and interference from the power supply or nearby may affect the normal operation of the module
|
|
2
|
Therefore, it is recommended to use a battery or power frequency transformer to stabilize the voltage obtained from the power supply of the module
|
|
3
|
Do not use switching power supplies (such as mobile phone chargers, and any other switching power supplies), power banks, and no working Class D amplifiers, microwave ovens, and other equipment nearby
|
|
4
|
Otherwise, the interference generated by these devices will affect the reception of this module.

Instructions for use:
1. Line connection
All functional outputs of this module are reserved for external ports. Users need to connect the corresponding line module to work properly.
<1>: Connect audio cable
The corresponding ports AGND, Output R, and Output L of the module are respectively connected to the ground of the audio transmission line, the left channel, and the right channel.
<2>: Connect the power cord
The corresponding ports GND and VCC of the module are respectively connected to the negative and positive poles of the power supply (battery). It is recommended to use batteries or other regulated power supplies for the power supply. Do not use switching power supply without filter (such as mobile phone charger, and other low-quality switching power supply), otherwise the interference generated by the power supply will affect the normal operation of this module. The normal operating voltage of this module is 3.0-5.0V, and the power supply voltage should not exceed this range.
<3>: Connect the button
All the buttons of this module are reserved for port leading out, and customers can access the corresponding function buttons according to their needs. Use the ordinary light touch buttons for the buttons, one end is connected to the corresponding button port of the module, and the other end is connected to the module GND or AGND terminal. Some buttons have a long press function (such as volume +/- long press for continuous +/- volume), long press for more than 2 seconds is effective.
<4>: Connect the antenna
The ANT port is used to connect the FM antenna. In order to receive (transmit) the FM signal better, it is recommended to connect a whip antenna with a length of 75 cm, and there should be no obstructions near the antenna as much as possible.
<5>: Connect to serial port (no need to connect without serial port control)
The module reserves a TTL level serial port control interface. Communication between the TTL serial port and this module requires the connection of the module's UART_RX, UART_TX and GND. You can use an external MCU (single chip microcomputer) or computer serial port to send commands to control the relevant functions of the module. Note: Because the serial port level of the computer is not TTL level, it is necessary to connect the RS323 level to TTL level replacement device or use the USB to TTL level serial port module to communicate with this module when communicating with the computer. Because the serial port command control module requires a certain amount of computer expertise, buyers who do not understand need not toss. For all information, please refer to the description of the baby. Customer service does not provide technical guidance in this regard.
2. Automatic search
This module comes with FM radio storage function. Long press "Auto Search" to start automatic search and store the available radio stations. After the search is completed, the first radio station P01 will be automatically played. The user can press the "previous radio station" or "next radio station" key to switch the searched radio station.
3. User settings
This module can set the backlight status and whether to listen to the campus radio frequency band according to the specific usage of the user. The setting method is as follows. Press and hold the VOL+, VOL- keys in the power-off state. After power-on, the LCD displays C1 to open the campus broadcast. C0 means to close the campus broadcast frequency band. The settings will take effect after restart. When setting the backlight state, press and hold the UP and DOWN radio buttons at the same time when the power is off, and the display B1 indicates that the backlight is always on, B0 indicates that the backlight is turned off for 20 seconds, and the setting takes effect after restarting. Change the setting state and repeat this step to switch. The factory setting is uniformly set to not open the campus broadcast frequency band, and the backlight goes off after 20 seconds of no operation.
4. Mono/Stereo
This module can flexibly set mono demodulation and stereo demodulation modes. The two solder joints of MONO on the back of the PCB board are connected together for mono demodulation mode, and disconnected for stereo demodulation mode.
5. Matters needing attention
1: The power supply voltage must not exceed the power supply voltage range of this module.
2: Do not touch the back components of the module during operation, so as not to affect the normal operation of this module or cause a short circuit to burn the module.
Scope of application: FM stereo radio, digital radio
