PCB ATtiny85: common questions

What microcontroller does the PCB ATtiny85 use?

The PCB ATtiny85 is built around the ATtiny85-20PU, from the AVR/Arduino family.

How big is the PCB ATtiny85?

The PCB ATtiny85 measures 80.3 × 58.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PCB ATtiny85?

25 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the PCB ATtiny85 design files?

From the tidus747/Proyectos_KiCAD repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the PCB ATtiny85 design in my own project?

Yes, under the terms of its GPL-3.0 license, which tidus747 chose for the repository.

Can I test firmware for the PCB ATtiny85 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.
