Vizitka: common questions
What microcontroller does the Vizitka use?
The Vizitka is built around the ATmega328P-AU, from the AVR/Arduino family.
How big is the Vizitka PCB?
The Vizitka measures 90 × 50 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Vizitka?
53 components, from 27 distinct parts. The full bill of materials is listed on this page.
Where can I download the Vizitka design files?
From the Meteopresscz/PCB_Public repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Vizitka design in my own project?
The repository has no license, so all rights stay with Meteopresscz. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Vizitka 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.
