What boards using the ATtiny85 are built for

ATtiny85: common questions

Where can I find a ATtiny85 reference design?

Each of the 2 boards on this page is a real design using the ATtiny85. 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 ATtiny85 use?

Most are built on AVR/Arduino (2).

How big is a typical board using the ATtiny85?

The median is 32.1 × 32.5 mm, and 100% are two-layer designs.

What is the most popular open source board using the ATtiny85?

By GitHub stars, 2-digit-Turbo-Display by wiretap-retro, with 12 stars.

Can I simulate one of these boards using the ATtiny85 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.
