1uO c v 2.2: common questions

What microcontroller does the 1uO c v 2.2 use?

The 1uO c v 2.2 is built around the TEENSY_3.2_USB_DAC_RESET, from the NXP family.

How big is the 1uO c v 2.2 PCB?

The 1uO c v 2.2 measures 149 × 28.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 1uO c v 2.2?

122 components, from 38 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the 1uO c v 2.2 design files?

From the rhinocerose/eurorack-designs repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the 1uO c v 2.2 design in my own project?

The repository has no license, so all rights stay with rhinocerose. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 1uO c v 2.2 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
