ChordOdes: common questions

What microcontroller does the ChordOdes use?

The ChordOdes is built around the Arduino_Nano_Socket, from the AVR/Arduino family.

How big is the ChordOdes PCB?

The ChordOdes measures 30.8 × 111.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ChordOdes?

52 components, from 22 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 ChordOdes design files?

From the oficinadesonido/miPrimerModular 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 ChordOdes design in my own project?

Yes, under the terms of its GPL-3.0 license, which oficinadesonido chose for the repository.

Can I test firmware for the ChordOdes without the hardware?

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