I have a problem in MP3-tf-16p module. When I power up it with a sd card it on and turn off. How to solve it . Please help me
Can you give a little more detail? What voltage are you supplying to it, do you have a 10uf capacitor in line with the vcc and gnd pins. What size SD card are you using and is it FAT32 formatted?
What speaker are you using? Are you using the IO pins to control the module or is it being controlled by an Arduino of some kind?
Can you post a picture of your setup or a wiring diagram?
Have you soldered the header pins of the MP3 player? How are you connecting wires to the MP3 player? Upload a picture.
What is the problem?
I solve the problem, I use a 10k resistor on the 8002 ic pin no.1 .
First I use the jumper wires, it creates lose connection. Then. I solderd wires
Good job
