Home automation: common questions

What microcontroller does the Home automation use?

The Home automation is built around the ATMEGA328PB-AU, from the AVR/Arduino family.

How big is the Home automation PCB?

The Home automation measures 72.4 × 58.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Home automation?

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

Where can I download the Home automation design files?

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

Can I use the Home automation design in my own project?

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

Can I test firmware for the Home automation 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.
