Card avr: common questions

What microcontroller does the Card avr use?

The Card avr is built around the ATtiny202-SS, from the AVR/Arduino family.

How big is the Card avr PCB?

The Card avr measures 90.2 × 53.3 mm, has 2 copper layers and is 0.8 mm thick.

How many components are on the Card avr?

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

Where can I download the Card avr design files?

From the McbeEringi/pcb-stuff repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Card avr design in my own project?

Yes, under the terms of its MIT license, which McbeEringi chose for the repository.

Can I test firmware for the Card avr 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.
