Phase interferometer: common questions

What microcontroller does the Phase interferometer use?

The Phase interferometer is built around the RP2040, from the RP2040/RP2350 family.

How big is the Phase interferometer PCB?

The Phase interferometer measures 54.3 × 76.1 mm, has 4 copper layers and is 0.8 mm thick.

How many components are on the Phase interferometer?

78 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the Phase interferometer design files?

From the mpkendall/phase-interferometer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Phase interferometer design in my own project?

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

Can I test firmware for the Phase interferometer 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.
