Senior design: common questions

What microcontroller does the Senior design use?

The Senior design is built around the Arduino_Nano_Every, from the AVR/Arduino family.

How big is the Senior design PCB?

The Senior design measures 50 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Senior design?

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

Where can I download the Senior design design files?

From the alaza252/senior_design repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Senior design design in my own project?

The repository has no license, so all rights stay with alaza252. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Senior design 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.
