Problems with inserting SD Card into DFPlayer Mini

Arcade Help
1

I am unsure if this has anything to do with a short circuit, but whenever I insert the SD Card into a DFPlayer Mini I have hooked up to my mini:bit, the red LED built into the module turns off, and the faint static sound that the speaker makes stops simultaneously. I then am unable to turn the module on again until I take out the SD Card, then the light turns on if I unplug the GND or VCC wire and plug it back in again.

Did you ever find a solution to this problem? I am using the Anmbest YX5200 DFPlayer Mini from Amazon (https://www.amazon.com/gp/product/B07JGWMPTF/ref=ask_ql_qh_dp_hza) and I’m having the exact same problem, but everywhere I check there does not seem to be a solution for this :frowning:.

Unfortunately, no. I originally thought my SD card was just corrupted as it was a little funky on my other devices, but the issue still persisted even after buying a completely new one.

I finally found that despite every source of documentation stating to name the file “001.mp3”, all files are supposed to be formatted as “0001.mp3” 0002.mp3" etc.

So did I after naming the only mp3 file 001, haha. Unfortunately, didn’t fix it :frowning:

Nope, unfortunately not. I left it since my last post and I just took it back out today to try and figure out what’s up with it (using an arduino right now.) I’ll keep you guys updated if I figure out anything.

Hello guys, any news regarding this?
I have the same issue, when I insert my sd card the built in led in the dp player mini turns off. To turn it back on, I have to disconnect the ground or 5v and remove the sd card.
Please let us know if you know why or how to solve it

I found a solution, might help with you as well. I was also facing same issue, whenever I insert SD card the led light goes off with no sound. I used a jumper cable to short GND pin and ADKEY_1 pin. Then I tried disconnecting the short connection and while SD card was already in, I gave the input voltage and then I connected both the pins again then it worked. So I think we need to add a push switch to activate everytime.
