Using SparkFun MP3 Player Shield with Arduino Wifi Rev 2

Sensors Sound & Audio

I’m attempting to use the SparkFun MP3 Player Shield (https://www.sparkfun.com/products/12660) with an Arduino Wifi Rev 2 (https://www.sparkfun.com/products/14871).

I’ve had a bit of a rough road. I’ve been following the MP3 Player Shield Hookup Guide V15 (https://learn.sparkfun.com/tutorials/mp … -guide-v15).

I have confirmed I have a v15 board, I’ve soldered on the suggested stackable shield headers (https://www.sparkfun.com/products/11417), stacked the SparkFun MP3 Player Shield on top of the Arduino Wifi Rev 2, inserted a SanDisk 16GB Ultra microSDHC Memory Card (https://smile.amazon.com/gp/product/B07 … UTF8&psc=1) fromatted as FAT32 and loaded with one file named track001.mp3 into the SparkFun MP3 Player Shield, finally got the FilePlayer Example Sketch to compile and load, and I keep getting the following error:

Free RAM = 4853 Should be a base line of 1017, on ATmega328 when using INTx

Can’t access SD card. Do not reformat.

No card, wrong chip select pin, or SPI problem?

SD errorCode: 0X20,0XFF

The only thing I’ve identified so far as a potential issue is that I don’t have any of the 2x3 ICSP pins on the Arduino Wifi Rev2 connected to the SparkFun MP3 Player Shield.

Questions:

  • Is this actually my issue?

  • Is there anything else I should try?

    Hi draco87.

    The MP3 Player Shield was designed to be used with a ATmega328 based board like our [RedBoard Qwiic or Arduino’s [Arduino Uno. Unfortunately it looks like it’s not compatible with the ATmega4809 chip the new Arduino WiFi Rev 2 uses. :-(](https://www.sparkfun.com/products/11021)](SparkFun RedBoard Qwiic - DEV-15123 - SparkFun Electronics)

    Thank you for letting me know the MP3 Player Shield isn’t compatible. I need to continue using my Arduino Wifi Rev 2 for my project, is there another product you could recommend that plays mp3s from a microSD card that would be compatible?

    Thanks in advance.

    The best thing I can recommend at this time would be the [MP3 Trigger. You can control it with digital I/O or via TTL serial.](MP3 Trigger - WIG-13720 - SparkFun Electronics)
