ResamplerBoard: common questions

What microcontroller does the ResamplerBoard use?

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

How big is the ResamplerBoard PCB?

The ResamplerBoard measures 70 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ResamplerBoard?

17 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the ResamplerBoard design files?

From the gibbi/PicoGPSDO repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ResamplerBoard design in my own project?

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

Can I test firmware for the ResamplerBoard 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.
