Teensy Beats Shield

Rendering from KiCad 5

I’ve been working on an audio step sequencer for the Hackaday Prize Musical Instrument Challenge.  The breadboard prototype is working nicely, and boards from JLCPCB should arrive this week.  The device is somewhat of a “shield” for the Teensy 3.6, incorporating elements from the Teensy audio shield, 2.4 inch TFT touch screen, microphone, additional flash, rotary encoders, APA102 LEDs, and a grid of pushbuttons.  I’m working heavily on firmware while waiting for PCBs.
