This is a Raspberry Pi Zero W hat/shield with USB MIDI input, stereo audio output, 3 user-configurable buttons and OLED display.
To use as an audio card, enable PWM audio output by adding `dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4` at the end of *config.txt* file.
Remeber that HDMI audio output is the default; use `raspi-config` to force output to 3.5mm audio jack.
If you can't find 47uF...
NeoPixel led strip controller, designed especially for led suits. It can:
- display animation - sequences of frames at regular (given) interval,
- switch animations on MIDI event - note on/off, velocity used for brightness adjust,
- MIDI over UDP over WiFi (UDP broadcast so far, but i'm working on multicast),
- use regular SD card to storage animations.

OBSOLETE: this version is obsolete. Check new version without the MIDI port, but with improved audio and cleaner schematic https://easyeda.com/account/project?project=2bca68b51d954e19b68cba485984fb42
This is a replacement board for Korg MicroKey 37 midi keyboard. ArduinoPro Micro and serial port expander (CJMCU-2317) has been used. Only one USB, no HUB like on the original.
P1 is theVCC and GND connector for the scan matrix
P2 is the 8 rows of the scan matrix
P3 is the column selector
P4 is the pitch and modulation wheel potentiometers
P5 is the octave selectro buttons and LEDs
