I'm using version 10 and I get a serial error when the pic tries to start the module , how can I fix this ? 1 button on the input of the pic one tone on the output of the module is the goal

Just had a play at getting one of these to work (I had an idea for a project using one and had just got two new boards from Temu). This didn't seem to work with an Arduino - and I swapped to an esp32 (for 3.3V) and still nothing. I used the component from the above link (and a simple initialise, PlayRandomAll)

I found an old project using a dfplayer (a few years old) that I got from Banggood - and it burst into life (Pachabel's Canon). The new board shows no sign of life (apart from a 'click' on sending a command) - the old board the blue 'playing' LED lights and all is good.

So - if you have a spare, might be worth trying that if you are still getting nothing...

Also note that the SD must be <= 32GB.

Also - with the speaker I used - it was virtually inaudible at volume < 20

The 'new' boards are marked v0.5.1 will have to google see if they need anything different to the old..

I then got some boards from amazon - and all good but with a red led instead of the blue..
Looks like the Temu boards are either faulty or have an old firmware version?
