Home automatics: common questions

What microcontroller does the Home automatics use?

The Home automatics is built around the Arduino_Pro_Mini, from the AVR/Arduino family.

How big is the Home automatics PCB?

The Home automatics measures 149 × 127 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Home automatics?

37 components, from 32 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 Home automatics design files?

From the ranseyer/home-automatics repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

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

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

Can I test firmware for the Home automatics 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.
