Project luminescence: common questions

What microcontroller does the Project luminescence use?

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

How big is the Project luminescence PCB?

The Project luminescence measures 70 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Project luminescence?

16 components, from 7 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 Project luminescence design files?

From the vindognz/project-luminescence repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Project luminescence design in my own project?

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

Can I test firmware for the Project luminescence 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.
