ATOM SPK is an audio player that adapts to the ATOM master control, with built-in I2S digital audio interface power amplifier chip NS4168, with automatic sampling rate detection, adaptive functions, and can effectively prevent audio signal distortion. Integrated TFCard card slot is convenient for saving and reading audio files. Provide 3.5mm headphone jack and external speaker interface, users can play audio through external headphones or speakers.
ATOM SPK Some IO conflict with ATOM Matrix's built-in hardware, so ATOM SPK is only applicable to ATOM LITE

made a internet radio and connect it to my 'old' stereo and added mp3 music on the SD Card, and it works perfect.
I am a newbie. I just want to play mp3 file from the micro-SD card and output through the headphone jack, remotely controlled by another M5Atom lite and this come in handy!
I wish there are block-based Uiflow coming soon enough but the Arduino IDE works just fine, just need to ask around from the expert.
And the button on M5Atom lite does NOT work when it's plugged into the SPK base (hopefully anyone could correct me that this is NOT the case!).
