This board is a digital "mixtape," designed to be a compact way to share a music playlist and recordings with friends.
Similar to a cassette, when given to others it has a surprise factor of not knowing what's up next.
Board was built up in December 2016, and general functionality (power regulation, bluetooth control, SD card, audio out) was confirmed.
- Plug-in bluetooth module (like the HC-06 or CC2540) allows for remote control with an phone or computer.
- Power comes from a rechargeable 18650 Li-ion battery.
- Teensy 3.2 is used as the microcontroller.
- Audio is single channel, 3W Class-D amplifier using a PAM8009DHR
