Inuino: common questions

What microcontroller does the Inuino use?

The Inuino is built around the IC--ATMEGA644PA-AU, from the AVR/Arduino family.

How big is the Inuino PCB?

The Inuino measures 68.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Inuino?

58 components, from 37 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 Inuino design files?

From the aiex718/Inuino repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Inuino design in my own project?

Yes, under the terms of its LGPL-2.1 license, which aiex718 chose for the repository.

Can I test firmware for the Inuino 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.
