LabNode-Nexus: common questions

What microcontroller does the LabNode-Nexus use?

The LabNode-Nexus is built around the RP2040, from the RP2040/RP2350 family.

How big is the LabNode-Nexus PCB?

The LabNode-Nexus measures 100 × 100 mm, has 4 copper layers and is 1.522 mm thick.

How many components are on the LabNode-Nexus?

252 components, from 64 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 LabNode-Nexus design files?

From the aleko-khomasuridze/LabNode-Nexus 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 LabNode-Nexus design in my own project?

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

Can I test firmware for the LabNode-Nexus 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.
