Pico 2HP: common questions

What microcontroller does the Pico 2HP use?

The Pico 2HP is built around the RP2350, from the RP2040/RP2350 family.

How big is the Pico 2HP PCB?

The Pico 2HP measures 70 × 30.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pico 2HP?

52 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 Pico 2HP design files?

From the rheslip/2HPico-Eurorack-Module-Hardware 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 Pico 2HP design in my own project?

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

Can I test firmware for the Pico 2HP 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.
