Final Board v3D: common questions

What microcontroller does the Final Board v3D use?

The Final Board v3D is built around the ATMEGA328PB-A, from the AVR/Arduino family.

How big is the Final Board v3D?

The Final Board v3D measures 79.3 × 87.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Final Board v3D?

59 components, from 32 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 Final Board v3D design files?

From the Petros-Kapetanios/Senior-Design 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 Final Board v3D design in my own project?

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

Can I test firmware for the Final Board v3D 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.
