Octave - Input: common questions

What microcontroller does the Octave - Input use?

The Octave - Input is built around the Raspberry_Pi_RP2040, from the RP2040/RP2350 family.

How big is the Octave - Input PCB?

The Octave - Input measures 106.8 × 57.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Octave - Input?

58 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Octave - Input design files?

From the takayoshiotake/octave-12-key-macropad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Octave - Input design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which takayoshiotake chose for the repository.

Can I test firmware for the Octave - Input without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
