De.freezweb.heizungssteuerung: common questions
What microcontroller does the De.freezweb.heizungssteuerung use?
The De.freezweb.heizungssteuerung is built around the ESP32-S3-WROOM-1-N4, from the ESP32 family.
How big is the De.freezweb.heizungssteuerung PCB?
The De.freezweb.heizungssteuerung measures 160 × 110 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the De.freezweb.heizungssteuerung?
114 components, from 37 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 De.freezweb.heizungssteuerung design files?
From the freezweb/de.freezweb.heizungssteuerung 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 De.freezweb.heizungssteuerung design in my own project?
The repository has no license, so all rights stay with freezweb. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the De.freezweb.heizungssteuerung 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.
