PortaRe0: common questions

What microcontroller does the PortaRe0 use?

The PortaRe0 is built around the RP2040#1, from the RP2040/RP2350 family.

How big is the PortaRe0 PCB?

The PortaRe0 measures 135 × 77 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the PortaRe0?

349 components, from 67 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 PortaRe0 design files?

From the 0Re0-8192/PortaRe0 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 PortaRe0 design in my own project?

The repository has no license, so all rights stay with 0Re0-8192. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PortaRe0 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.
