MainBoard: common questions

What microcontroller does the MainBoard use?

The MainBoard is built around the RP2040, from the RP2040/RP2350 family.

How big is the MainBoard PCB?

The MainBoard measures 194 × 36 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MainBoard?

78 components, from 46 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 MainBoard design files?

From the sabas1080/DesignLab-Builds-2023-Education 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 MainBoard design in my own project?

The repository has no license, so all rights stay with sabas1080. 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 RP2040/RP2350 firmware against it before you order a PCB.
