From the project

WARNING!!! This is a README created in particular only for week 1 on Thirdspace so that we can ship the project. Future README versions will be far more advanced.

A sophisticated way of growing whatever kind of plant (only legal ones :}) from your living room, balcony, even your bedroom or wherever you want!

The idea of the project is to have a work-free environment where the user only monitors his plants from the website and we the developers are resposnible for making everything functional for healthy and low-cost plant growing.

GrowHub: common questions

What microcontroller does the GrowHub use?

The GrowHub is built around the ESP32-S3-WROOM-1U-N16R8, from the ESP32 family.

How many components are on the GrowHub?

139 components, from 57 distinct parts. The full bill of materials is listed on this page.

Where can I download the GrowHub design files?

From the Ajakovski/GrowHub repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the GrowHub design in my own project?

Yes, under the terms of its MIT license, which Ajakovski chose for the repository.

Can I test firmware for the GrowHub 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.
