====== Electrosmith Daisy ======

===== Hardware =====
==== Seed ====
Features:

  * ARM Cortex-M7 @ 480 MHz (STM32)
  * stereo audio I/O (96 kHz @ 24-bit)
  * 2 DAC outs (12-bit)
  * 12 ADC ins
  * [[I2C]], [[SPI]], [[USART]], [[I2S]], SAI, [[SDIO]]
  * USB data pins broken out

GPIO pins are 5 V tolerant except for pins 24, 25, 28, 39, and 30. Audio inputs are AC coupled and accept at most 3.6 Vpp (-1.8 V -- +1.8 V). Vin can range from +4 to +17 V. 

For all applications, AGND (pin 20) must be connected to DGND (pin 40).

==== Pod ====
A breakout board for the Seed with the following I/O components:

  * stereo line in
  * stereo line out
  * headphone out with dedicated volume control
  * TRS [[MIDI]] in
  * microSD card slot
  * 2 push buttons
  * 2 pots
  * 2 RGB LEDs
  * 1 encoder with push button 

Additionally, the following pins on the Seed are broken out:

  * D7/[[SPI]]1 CS
  * D8/[[SPI]]1 SCK
  * D9/[[SPI]]1 MISO
  * D10/[[SPI]]1 MOSI
  * D11/[[I2C]] SCL
  * D12/[[I2C]] SDA
  * A7/D22 (ADC 7)
  * A1/D16 (ADC 1)
  * 3.3 V Analog
  * 3.3 V Digital
  * Vin
  * GND
