Prototype-1: common questions

What microcontroller does the Prototype-1 use?

The Prototype-1 is built around the ESP32-POE, from the ESP32 family.

How big is the Prototype-1 PCB?

The Prototype-1 measures 230 × 150 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Prototype-1?

17 components, from 15 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 Prototype-1 design files?

From the mylife-home/mylife-home-devices 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 Prototype-1 design in my own project?

Yes, under the terms of its GPL-3.0 license, which mylife-home chose for the repository.

Can I test firmware for the Prototype-1 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.
