DFPlayer Not Working

It looks like you have Rx going to Rx. Also what size SD card are you using? If it’s bigger than 32gb, it won’t work. I have used a bunch of these DFPlayer modules for my projects and though it says it will work with 5V, I found that is not always the case. 3.3V with a 47uf electrolytic capacitor, should work. Also that module is current hungry so the 3.3V coming from the Arduino might not give sufficient current.
