4 open source boards using the ATtiny404-SS
Real designs built with the ATtiny404-SS, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

Microcontrollers on boards using the ATtiny404-SS
What boards using the ATtiny404-SS are built for
ATtiny404-SS: common questions
Where can I find a ATtiny404-SS reference design?
Each of the 4 boards on this page is a real design using the ATtiny404-SS. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the ATtiny404-SS use?
Most are built on AVR/Arduino (4).
How big is a typical board using the ATtiny404-SS?
The median is 40.9 × 33.1 mm, and 100% are two-layer designs.
What is the most popular open source board using the ATtiny404-SS?
By GitHub stars, Stepper by hisashin, with 47 stars.
Can I simulate one of these boards using the ATtiny404-SS before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
