NERD-HPC: common questions

What microcontroller does the NERD-HPC use?

The NERD-HPC is built around the RP2040, from the RP2040/RP2350 family.

How big is the NERD-HPC PCB?

The NERD-HPC measures 137 × 72 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the NERD-HPC?

153 components, from 29 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 NERD-HPC design files?

From the TTtensan/NERD-HPC 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 NERD-HPC design in my own project?

Yes, under the terms of its GPL-3.0 license, which TTtensan chose for the repository.

Can I test firmware for the NERD-HPC 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.
