Kontroler: common questions
What microcontroller does the Kontroler use?
The Kontroler is built around the ATTINY841-SSU, from the AVR/Arduino family.
How big is the Kontroler PCB?
The Kontroler measures 147 × 78 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Kontroler?
38 components, from 25 distinct parts. The full bill of materials is listed on this page.
Where can I download the Kontroler design files?
From the domenipavec/traffic-light repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Kontroler design in my own project?
The repository has no license, so all rights stay with domenipavec. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Kontroler 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.
