Garden box: common questions

What microcontroller does the Garden box use?

The Garden box is built around the ESP32-POE, from the ESP32 family.

How big is the Garden box PCB?

The Garden box measures 230 × 150 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Garden box?

66 components, from 16 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 Garden box 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 Garden box 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 Garden box 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.
