Hermes Pico: common questions
What microcontroller does the Hermes Pico use?
The Hermes Pico is built around the TPS5430DDAR, from the RP2040/RP2350 family.
How big is the Hermes Pico PCB?
The Hermes Pico measures 53 × 65 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Hermes Pico?
21 components, from 17 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 Pico design files?
From the raybello/KICAD-PCBs repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Hermes Pico 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 Pico 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.
