Dfplayer with a protoboard
I am currently working on a mp3 player. It is my first official project and from this point it has been working alright. I had everything set up on a breadboard just to prototype, and once it was working the way I wanted, I decided to move everything on a perfboard.
This is where the Dfplayer comes in. The first thing I made sure was working for the Dfplayer. I had sample code that I tested and it worked. After that was good I soldered the button, an OLED screen. Everything was working except for the player, so I decided to resolder it just to make sure I didn’t accidentally bridge anything previously. After I did that I noticed an issue where if the vcc and gnd is connected to the player then the whole esp32 shuts down.
I figured I somehow fried the dfplayer module, and switched it out for another. Before I did that I double checked that it worked with a breadboard and when it did I decided to add it to the perfboard. The same issue is occurring now. Does anybody know how to fix it?
Tldr: when I connect my Dfplayer to gnd and vcc on a perfboard the whole esp32 shuts down. If the module is on a breadboard it works properly.
