Ornament2021: common questions

What microcontroller does the Ornament2021 use?

The Ornament2021 is built around the ATmega328P-PU, from the AVR/Arduino family.

How big is the Ornament2021 PCB?

The Ornament2021 measures 149.5 × 149.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ornament2021?

131 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Ornament2021 design files?

From the JamesMorrisELCT/Ornament2021 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Ornament2021 design in my own project?

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

Can I test firmware for the Ornament2021 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.
