ATtiny85-Smart Diya: common questions

What microcontroller does the ATtiny85-Smart Diya use?

The ATtiny85-Smart Diya is built around the ATtiny85-20P, from the AVR/Arduino family.

How big is the ATtiny85-Smart Diya PCB?

The ATtiny85-Smart Diya measures 57.1 × 57.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ATtiny85-Smart Diya?

9 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the ATtiny85-Smart Diya design files?

From the tejashviraj19/PCB-Design-Lab repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ATtiny85-Smart Diya design in my own project?

The repository has no license, so all rights stay with tejashviraj19. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ATtiny85-Smart Diya 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.
