Just purchased one plugged it in but having problems.
When I plug in a 9v power supply and I have a 64gb micro sd sandisk ultra inserted, the led flashes approximately 6 to 8 times very fast. no sound through headphones. It then flashes about every 3 secs. When I press the button nothing happens.
The sound files are from either robertsonics or sparkfun.
I have tried using this format 0001_Number.wav
and the standard one 001_Number.wav
but no difference.
I have tried copying files using mac and pc with no difference just a rapid set of flashes then a slow pulse.
Any ideas on how to get it working. I have plugged the same headphone and lead into a adafruit audio fx sound board and headphones work.
