The KiCad project lives in the PubInv/Ox repository on GitHub; these links point at the commit this page was built from.
O: common questions
What microcontroller does the O use?
The O is built around the Arduino_Due_Shield, from the AVR/Arduino family.
How big is the O PCB?
The O measures 140 × 190 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the O?
199 components, from 61 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 O design files?
From the PubInv/Ox 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 O design in my own project?
Yes, under the terms of its AGPL-3.0 license, which PubInv chose for the repository.
Can I test firmware for the O 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.
