This is an opensource hardware/software project. It’s a DIY logic analyzer build around a raspberrypi pico.

With a pico2, you can achieve 400MHz sample rate.  
Hardware is pretty simple, because, except the pico, they are only a few component (mostly level shifters).

A YT vid ([they are many](https://www.youtube.com/results?search_query=gusman+pico+logic+analyzer)):

**Under the hood:** it’s been a while I am lurking at logic analyzer’s. But they are too expensive or they look too much like a cheap chinese thingie and my personal background is too light in that matter. But, I tend to believe that, with such a tool, I will better understand the under laying protocols (I2C, SPI, I2S …), the data formats, the timings and so on.  
So, I think I will order a PCB (I’ve already got a pico in my drawer).

I’ve ordered 5 of them with SMD components assembled.

If anyone here is interested please notify me. Additional parts needed are a RaspBerryPi Pico, headers and switch.
