Greenhouse: common questions

What microcontroller does the Greenhouse use?

The Greenhouse is built around the XAIO ESP32-C3, from the ESP32 family.

How big is the Greenhouse PCB?

The Greenhouse measures 113.2 × 36.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Greenhouse?

26 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Greenhouse design files?

From the garthwebb/greenhouse repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Greenhouse design in my own project?

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

Can I test firmware for the Greenhouse 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.
