EMC-Assignment-2: common questions

What microcontroller does the EMC-Assignment-2 use?

The EMC-Assignment-2 is built around the ATMEGA16U2-MU, from the AVR/Arduino family.

How big is the EMC-Assignment-2 PCB?

The EMC-Assignment-2 measures 82.5 × 61.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the EMC-Assignment-2?

87 components, from 43 distinct parts. The full bill of materials is listed on this page.

Where can I download the EMC-Assignment-2 design files?

From the mildcream/EMC-Assignment-2 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the EMC-Assignment-2 design in my own project?

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

Can I test firmware for the EMC-Assignment-2 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.
