About the Thermostat PCB

Thermostat is an open source ESP32 PCB design by fortcollinscreatorhub, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 93.6 × 83.1 mm, with 54 components from 28 distinct parts.

Its main chip is the ESP32-DevKitC, from the ESP32 family. Other key parts include the DS18B20. By type, the board carries 17 resistors, 16 capacitors, 5 switches, 5 diodes, 2 ICs and 2 transistors.

It belongs with the iot & wireless designs in this gallery.

From the project

Custom thermostats: PCBs, ESP-IDF & arduino code, ...

This repository contains files for the custom thermostats used at the Fort Collins Creator Hub.

This project uses git submodules, unfortunately. To clone the repository, run:

If you wish to push back to the github repo, you probably want to clone with ssh, or edit .git/config to use ssh URLs after cloning, e.g.:

Even if you clone using the ssh URL, you'll still need to edit the remote definition for each submodule after the initial clone operation.

Thermostat: common questions

What microcontroller does the Thermostat use?

The Thermostat is built around the ESP32-DevKitC, from the ESP32 family.

How big is the Thermostat PCB?

The Thermostat measures 93.6 × 83.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Thermostat?

54 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Thermostat design files?

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

Can I use the Thermostat design in my own project?

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

Can I test firmware for the Thermostat 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.
