Ornament & Crime Eurorack

Made a one off to test a new panel design, the panel is brand new and the o_C has only seen use as a test machine. I will not be doing any more production runs.

I will be offering a few PCB's and panels soonish for the DIY crowd.

Calibrated on a 60000 Counts DMM and tested with burn in.
+/- 0.0001 Vdc 

PCB version 2E

Firmware Version v1.3.6

White OLED display

Ship's from Taiwan via 1st Class airmail with real time tracking.
Specs:

•  (Freescale MK20DX256 / 32-bit ARM Cortex M4).
• 4x precision CV outputs, 16-bit (TI ).
• output range: -3v/+6v, “in-the-loop” compensated, for proper DC accuracy (+ 9 calibration points per channel, settable in firmware); +/- 0.2mV error across a 9 octave pitch CV range is achievable.
• 4x CV inputs, -3.5v/+6.5v, 12bit, 100k input impedance.
• 4x trigger/gate inputs, threshold ~ 2.5v, > 100k input impedance.
• two rotary encoders, with built-in push switches.
• two push buttons.
• 128 x 64 pixel 1.3” OLED display (SPI / SH1106 driver chip).
• trigger-to-quantised-output latency < 100 microseconds.
• 16.67kHz internal timer (CPU overclocked to 120MHz), which is also the DAC update rate. the ADC is also read at 16.67kHz but in several of the o_C “apps”, 16 values are averaged to remove noise, meaning that the effective sample rate for CV inputs is about 1 kHz. Digital (gate/trigger) inputs are read at 16.67 KHz — this ensures very low latency.
• +/-12V power only, ca. 85mA power draw on +12V bus, < 10mA on -12V bus)
