Smart-Home-Controller: common questions

What microcontroller does the Smart-Home-Controller use?

The Smart-Home-Controller is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Smart-Home-Controller PCB?

The Smart-Home-Controller measures 100 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Smart-Home-Controller?

11 components, from 5 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 Smart-Home-Controller design files?

From the Ajith-Anand-R/Smart-Home-Controller repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Smart-Home-Controller design in my own project?

Yes, under the terms of its MIT license, which Ajith-Anand-R chose for the repository.

Can I test firmware for the Smart-Home-Controller without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
