what makes the Flea-Scope so particularly interesting to me is that you get I think 9 channels worth of digital inputs all at once. That is hard to beat for the price.

Regarding raw specs, it seems to be much better in most regards compared to the mentioned Fnirsi-138 Pro.

Rich designed it with trigger IO pins to be able to easily chain them. While the UI doesn't support managing multiple Flea-Scopes at once, you can just open the UI multiple times, which does seem like a reasonable option to me.

As as others have pointed out before, there's just no alternatives in this form factor. The scope is tiny, and for what it is it packs quite a punch. 3.3V and 5V are standard logic levels which will suffice for quite a lot of basic probing. Being made for students, it does likely everything that would be required of it in an educational environment. How well this pans out in real-life we'll see soon.

Granted that with enough money and space at hand there are much better options out there.

On page 9 of the linked document Rich also addresses this and calls for the use of a full-speed usb isolator

Recording, exporting and interpreting waveforms doesn't seem to be amongs the objectives of the scope interface.

Over on hackaday [0] Rich explains that you can however easily grab the data directly from the serial port using python and thus record it:

> (07/28/2024) Sorry, there is no protocol analysis -- just digital display. You can invoke a "scope" command by python or something, and get the data yourself in binary -- I have an example of that in StickOS2 repo python/scope.py, but it is very rough. (Analog has additional challenges of having to do calibration, but digital is easy.)

In his presentation video [0] Rich explicitly states that his goal is to make electronics approachable for the younger generation. A low barrier of entry in almost all directions is a key component in that in my opinion.

For yet another comparison, scoppy is a similar project: https://github.com/fhdm-dev/scoppy

Correct. What should I replace "FOSS" with so that the title stays short and concise but correctly reflects the licensing/rights situation?

I'm very new to posting on this platform.
