Home-Automation-System: common questions

What microcontroller does the Home-Automation-System use?

The Home-Automation-System is built around the NANO, from the AVR/Arduino family.

How big is the Home-Automation-System PCB?

The Home-Automation-System measures 86.4 × 90.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Home-Automation-System?

81 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the Home-Automation-System design files?

From the 0101shift/Home-Automation-System repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Home-Automation-System design in my own project?

The repository has no license, so all rights stay with 0101shift. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Home-Automation-System 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.
