Mainboard: common questions

What microcontroller does the Mainboard use?

The Mainboard is built around the ATmega2560-16AU, from the AVR/Arduino family.

How big is the Mainboard PCB?

The Mainboard measures 120 × 120 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mainboard?

151 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mainboard design files?

From the MUNAKATA-EPC/Artemis_2023 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Mainboard design in my own project?

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

Can I test firmware for the Mainboard 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.
