SmartHomeSystem: common questions

What microcontroller does the SmartHomeSystem use?

The SmartHomeSystem is built around the ATmega32A-P, from the AVR/Arduino family.

How big is the SmartHomeSystem PCB?

The SmartHomeSystem measures 155 × 136.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SmartHomeSystem?

35 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the SmartHomeSystem design files?

From the danielopaleye01/SmartHomeSystem repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SmartHomeSystem design in my own project?

The repository has no license, so all rights stay with danielopaleye01. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the SmartHomeSystem 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.
