Smarthome controller: common questions

What microcontroller does the Smarthome controller use?

The Smarthome controller is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Smarthome controller PCB?

The Smarthome controller measures 100 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Smarthome 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 Smarthome controller design files?

From the Gokul3611/smarthome-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 Smarthome controller design in my own project?

Yes, under the terms of its MIT license, which Gokul3611 chose for the repository.

Can I test firmware for the Smarthome 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.
