DuPal V3: common questions

What microcontroller does the DuPal V3 use?

The DuPal V3 is built around the Pico, from the RP2040/RP2350 family.

How big is the DuPal V3 PCB?

The DuPal V3 measures 116.8 × 73.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DuPal V3?

128 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the DuPal V3 design files?

From the DuPAL-PAL-DUmper/DuPAL_Board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the DuPal V3 design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which DuPAL-PAL-DUmper chose for the repository.

Can I test firmware for the DuPal V3 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.
