Hermes v1: common questions

What microcontroller does the Hermes v1 use?

The Hermes v1 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Hermes v1 PCB?

The Hermes v1 measures 22 × 46.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Hermes v1?

31 components, from 20 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 Hermes v1 design files?

From the raybello/KICAD-PCBs 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 Hermes v1 design in my own project?

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

Can I test firmware for the Hermes v1 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.
