Smart home automations: common questions

What microcontroller does the Smart home automations use?

The Smart home automations is built around the ESP32-PICO-D4, from the RP2040/RP2350 family.

How big is the Smart home automations PCB?

The Smart home automations measures 231 × 175.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Smart home automations?

50 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Smart home automations design files?

From the Sindhujashree-17/smart_home_automations repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

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

The repository has no license, so all rights stay with Sindhujashree-17. Use it as a reference, and ask the author before reusing the design.

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

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
