Circuit Module and It’s Remote Control

The main attraction is its cost. The board cost only 120 Rupees( 3$) with all 3 Connectors.

Audio Board Rs. 40 Only.

Transformer (0-9) 1 Amp.Rs. 40 Only.

IR Sensor, IC7805, Capacitor (1000MFD 16 to 25 volt-2) and IN 4007 (4 Diodes) Rs. 20 Only.

The board circuit diagram is so simple that there are a very few connections. Some of the connections are:-

Connector-13.3V - Power for IR sensor (Same as in Picture-3)IR - IR data line of IR sensorGND - Ground of IR sensorPLAY - switch connection for playVOL- - switch connection for vol -PMCH - switch connection for mode(Radio/USB)VOL+ - switch connection for vol +R - Right channel output to audio ampGND - groundL - Left channel output to audio amp

Connector-2GND - USB GroundDP - USB DATA +DM - USB DATA -5V - USB 5V

Connector-3 (For SD card connection)

Ifyou have plan for use only Pen Drive for songs then there are no requirement for Connector-3.You can use your Memory Card using Memory card reader and insert it in USB port.

CSDATACMDCLKDET3.3V

The other main features are an built in FM receiver and you can also control FM with remote control User Friendly Auto Search & Save Station Operation Available. The player can read up to 1999 songs.

PRODUCT INFORMATION OF Vire (http://www.vire.net.cn) USB MP3 player board:

A) Play the FM channelsB) Display The Song NumberC) Numerical Key Input Operation for Song Selection.D) FM Radio : 87.5 ¨C 108.0 MHzE) Auto Radio Station Search Operation.F) User Friendly Auto Search & Save Station Operation Available.G) Numerical Display For Volume.H) 188.8 LED Module Display.I) Rotated Volume Control Key could be connectedi)   4/6 Keys On Productii)  Select Forwardiii) Select Backwardiv) Volume Upv)  Volume Down

First you need 5 Volt and 9 Volt Power Supply. Here is complete diagram of IC 7805 5 Volt Power Supply for Usb Mp3 Module Circuit.

If you are using any external Amplifier or Computer Speaker then you can use 5 Volt Mobile charger as power supply for Usb Mp3 module. But be careful when connects charge pins make sure + and – pins have in right way otherwise board may be damage.

Circuit Diagram of 7805 5 Volt Power Supply for 0-9

The +5 volt power supply is based on the commercial 7805 voltage regulator IC. This IC contains all the circuitry needed to accept any input voltage from 8 to 18 volts and produce a steady +5 volt output, accurate to within 5% (0.25 volt). It also contains current-limiting circuitry and thermal overload protection, so that the IC won't be damaged in case of excessive load current; it will reduce its output voltage instead.

The 1000µf electrolytic capacitor serves as a "reservoir" which maintains a reasonable input voltage to the 7805 throughout the entire cycle of the ac line voltage. The four rectifier diodes keep recharging the reservoir capacitor on alternate half-cycles of the line voltage, and the capacitor is quite capable of sustaining any reasonable load in between charging pulses.

Detail of IR Sensor used in Mp3 Player for Remote Control

Full Name – IR Sensor Receiver with Metal case

Note:-Please use same Sensor with Metal case for Mp3 player.

Notes.

Use 1st pin as IR or RI Signal . Use 2nd pin as GND(-). 3rd pin to 3.3 Volt from Usb mp3 player module or circuit.

Complete Connection Diagram of Usb Mp3 Player Circuit Module with all Pin Details

Here you can see TackTileButtons connection in picture if you are using Remote control only then there are no need any connection for buttons because all control like volume up down Next Previous control with Remote easily. I publish these buttons connection only for knowledge view.

Note:- In picture you can see starting pins ( L G R). These pins are for Left Audio, Ground and Right Audio. If you have plan for use same power supply in both Audio Board and This mp3 player circuit then don’t connect pin G (Ground) to any point otherwise output sound may be not clear. Use Both L and G (Gnd) if you are using outside Audio system Like computer Speaker or any Amplifier device. Computer speakers pin have three points so you can use all three points (L, G and R). See Picture

6 watt 9 to 12 Volt Audio Amplifier circuit diagram for Mp3 player using TA7222A IC

Here is complete easy to understand amplifier circuit for create external audio amplifier with good quality sounds. You can use Mp3 player Module circuit audio output as input in this circuit.

More Description:Here is the circuit diagram of a 6W amplifier using the TA7222AP from Toshiba.TA7222AP is an excellent integrated audio amplifier which can deliver 5.8W to a 4 Ohms load at 12V supply voltage. The IC has very good features like, muting function, low distortion, high ripple rejection, short circuit protection, thermal shut down etc. This amplifier can be operated from 9 to 12V and this makes it ideal for car radio mp3 playersapplications.

Notes.

The circuit can be assembled on a Vero board. Use 12V DC for powering the circuit. The IC must be heatsinked. Speaker can be a 4 ohms one. For optimum performance input and output must be separately grounded.
