Heating controller: common questions
What microcontroller does the Heating controller use?
The Heating controller is built around the ATmega328PB-A, from the AVR/Arduino family.
How big is the Heating controller PCB?
The Heating controller measures 100 × 50 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Heating controller?
145 components, from 56 distinct parts. The full bill of materials is listed on this page.
Where can I download the Heating controller design files?
From the lucanastasio/myHomeAutomation repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Heating controller design in my own project?
The repository has no license, so all rights stay with lucanastasio. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Heating controller without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
