MCU2: common questions

What microcontroller does the MCU2 use?

The MCU2 is built around the ATmega328P-A, from the AVR/Arduino family.

How big is the MCU2 PCB?

The MCU2 measures 49.4 × 37.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MCU2?

20 components, from 17 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 MCU2 design files?

From the Kenkneeshio/SeniorDesign-Team9 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 MCU2 design in my own project?

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

Can I test firmware for the MCU2 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.
