Wall mounted room temperature sensor - Wifi: common questions

What microcontroller does the Wall mounted room temperature sensor - Wifi use?

The Wall mounted room temperature sensor - Wifi is built around the ESP32-WROVER-IE, from the ESP32 family.

How big is the Wall mounted room temperature sensor - Wifi PCB?

The Wall mounted room temperature sensor - Wifi measures 107 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Wall mounted room temperature sensor - Wifi?

50 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Wall mounted room temperature sensor - Wifi design files?

From the RomLab/pcb-system-for-underfloor-heating-v2.0 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Wall mounted room temperature sensor - Wifi design in my own project?

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

Can I test firmware for the Wall mounted room temperature sensor - Wifi 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.
