Pico_Debug_Stack

Warning: I have not sent this to JLCPCB yet. I am waiting for the Supreme Court to tell Trump his tariffs are illegal. I hope there will be a two-week window in which I can submit this without tariffs. I don't need it until Spring Quarter (March 2026).

This project is for debugging Raspberry Pi Pico projects. You unplug your Pico from its motherboard (your PCB that uses a Pico), plug it into the Pico_Debug_Stack, and plug the stack into your board. This hardware project provides the LogicAnalyzer sampling up to 400 MHz and a Debug Probe to make your Pico debugging easier. It uses two of the new RP2354B-A4 processors. These days, logic analyzers are not used very much because the parasitics of the wires connecting them to the device under test make the results incorrect with the speeds of logic commonly used now. This board provides short leads on a PCB, so LogicAnalyzer measurements are much closer to reality for your Pico project.
