Smart home: common questions

What microcontroller does the Smart home use?

The Smart home is built around the ESP-12, from the ESP8266 family.

How big is the Smart home PCB?

The Smart home measures 74 × 64 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Smart home?

72 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Smart home design files?

From the BajaCali/smart-home repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Smart home design in my own project?

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

Can I test firmware for the Smart home without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
