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
-
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).
