SmartHeater-CTRLModule: common questions

What microcontroller does the SmartHeater-CTRLModule use?

The SmartHeater-CTRLModule is built around the ATmega328P-A, from the AVR/Arduino family.

How big is the SmartHeater-CTRLModule PCB?

The SmartHeater-CTRLModule measures 71 × 62 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SmartHeater-CTRLModule?

15 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the SmartHeater-CTRLModule design files?

From the ghostking2802/SmartHeater-CTRLModule repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SmartHeater-CTRLModule design in my own project?

The repository has no license, so all rights stay with ghostking2802. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the SmartHeater-CTRLModule 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.
