Myhome: common questions

What microcontroller does the Myhome use?

The Myhome is built around the ESP32-WROOM-32D, from the ESP32 family.

How big is the Myhome PCB?

The Myhome measures 125 × 75 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Myhome?

55 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Myhome design files?

From the rojer/myhome repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Myhome design in my own project?

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

Can I test firmware for the Myhome 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.
