terminal_tedium

raspberry pi 2 / zero / pi a+ / b+ eurorack stereo DAC (PCM5102a) or codec (wm8731) breakout board *

• 4x digital inputs (100k input impedance; threshold > 3V)
• 2x digital outputs (~ 6V )
• 6x resp. 8x CV inputs (100k input impedance; 12 bit, +/- 5V range)
• 2x audio outputs (10VPP, 16bit / 48kHz)
• 2x audio inputs (50k input impedance, 16bit / 48kHz -- wm8731 only)

build info, see here: https://github.com/mxmxmx/terminal_tedium/wiki

pin usage:

wm8731 (blue) / pcm5102a (pink) :
