MXA115 10-BUTTON TRIGGERED MP3 PLAYER (WITHOUT SENSOR AND MICRO SD CARD)

This circuit is a MP3 player which can be connect the sensor for control the operation of
circuit. This circuit can be installed to a variety of tasks such as alarm circuit, reception
circuit, etc.
TECHNICAL DATA- Power supply : 5VDC.- At standby stage the circuit consumes about 25mA and at working stage about 300mA.
at speaker 8-ohm 0.25W.- There are two types of message play: Play Only the message no.1 and Play the message
One to One Click (sort).- It can be connect the external sensor for start the operation of circuit.- Support MP3 and WMV file (FAT16 and FAT32 file system)- Maximum support 32GB of the micro SD card.- Build-in on-board audio power amplifier 3 watts.- There is the external signal connector for connect the external amplifier.- PCB dimensions : 2.45 in x 3.01 in.(mainboard)
CONNECTING POINTS FOR APPLICATION- +5V- point is for connecting to a 5-VDC power supply.- SP point is for connecting to speaker 8-ohm 0.25-3W.- SW1-SW10 switch are selecting the message- PAUSE switch is pause the message or start playing the message.- A switch : short press to play previous or long press to decrease volume.- B switch : short press to play next or long press to increase volume.- SEN (+,G,IN) is used for connect the sensor (PIR, Coin machine and Switch, etc.).- OUT (L,G,R) is used for connect the external amplifier. For VRL and VRR are control
the volume level for the external amplifier.- + G 8 20 point is used for the factory only.- A,B point is used for the factory only (normally this point will jump at B point).- LP,1 point is used for select the operation of SW1 and sensor.
1.If jumping at “1” position, the circuit will play the message no.1 only.
2.If jumping at “LP” position, the circuit will play the message One to One Click
with the message will start number 1 to number 10 and restart again.
NOTE:- In case of jumping LP,1 point at “1”, SW1 switch and sensor will be play only the
message no.1. While the circuit is playing, if the user is press SW1 switch or sensor
detecting, the circuit do not start the new message. It will start the new message when the
old message is stop playing.- In case of jumping LP,1 point at “LP”, the circuit will play the message One to One Click
with the message will start number 1 to number 10 and restart again.- SW2 to SW10 switch are select the message. In case of the circuit is playing, if the user is
press the switch, the circuit will start playing the new message immediately following the
