RP2040-Logic-Analyzer: common questions

What microcontroller does the RP2040-Logic-Analyzer use?

The RP2040-Logic-Analyzer is built around the RP2040, from the RP2040/RP2350 family.

How big is the RP2040-Logic-Analyzer PCB?

The RP2040-Logic-Analyzer measures 55.2 × 24.4 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RP2040-Logic-Analyzer?

50 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the RP2040-Logic-Analyzer design files?

From the BlackPancakes/RP2040-Logic-Analyzer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the RP2040-Logic-Analyzer design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which BlackPancakes chose for the repository.

Can I test firmware for the RP2040-Logic-Analyzer without the hardware?
