Motherboard 2023: common questions

What microcontroller does the Motherboard 2023 use?

The Motherboard 2023 is built around the ARDUINO_PRO_MINI, from the AVR/Arduino family.

How big is the Motherboard 2023 PCB?

The Motherboard 2023 measures 241.5 × 74.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Motherboard 2023?

86 components, from 25 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 Motherboard 2023 design files?

From the RoanTractor/Tractor-Team-EL 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 Motherboard 2023 design in my own project?

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

Can I test firmware for the Motherboard 2023 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.
