ATtiny: common questions

What microcontroller does the ATtiny use?

The ATtiny is built around the ATtiny1604-SS, from the AVR/Arduino family.

How big is the ATtiny PCB?

The ATtiny measures 86 × 77 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ATtiny?

11 components, from 9 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the ATtiny design files?

From the Tert2/KiCAD repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the ATtiny design in my own project?

The repository has no license, so all rights stay with Tert2. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ATtiny 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.
