Mainboard2.0: common questions

What microcontroller does the Mainboard2.0 use?

The Mainboard2.0 is built around the ARDUINO_MEGA2560_REV3_-_RETAIL, from the AVR/Arduino family.

How big is the Mainboard2.0 PCB?

The Mainboard2.0 measures 94 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mainboard2.0?

42 components, from 21 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 Mainboard2.0 design files?

From the kapibaratomo/Soda_DENGIKEN repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Mainboard2.0 design in my own project?

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

Can I test firmware for the Mainboard2.0 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.
