CorboIron: common questions

What microcontroller does the CorboIron use?

The CorboIron is built around the Arduino_nano, from the AVR/Arduino family.

How big is the CorboIron PCB?

The CorboIron measures 78.7 × 99.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CorboIron?

101 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the CorboIron design files?

From the bjohan/CorboIron repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the CorboIron design in my own project?

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

Can I test firmware for the CorboIron 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.
